Abstract :

Heterojunction photocatalysts, which consist of two or more semiconductors, have garnered significant attention owing to their extensive benefits, including a broad-spectrum response, efficient carrier separation and migration, as well as robust redox capabilities. Among the myriad of semiconductors, graphitic carbon nitride (g-C3N4) and zinc indium sulfide (ZnIn2S4) have been extensively researched due to their low toxicity, straightforward and scalable synthesis processes, controllable microstructures, and exceptional chemical stability. Recently, there has been a trend towards integrating these two semiconductors to complement each other's strengths. Consequently, a systematic summary and outlook on g-C3N4/ZnIn2S4 heterojunction photocatalysts is both urgent and valuable. This review summarizes the advancements in the g-C3N4/ZnIn2S4 heterojunctions in the last 10 years. We first analyzed the charge-transfer mechanisms in the type-I, type-II, Z-scheme and S-scheme heterojunctions. Then the typical synthesis methods employed for creating g-C3N4/ZnIn2S4 heterojunctions are introduced. Subsequently, we delve into the regulation strategies for g-C3N4/ZnIn2S4 heterojunctions, including morphology optimization, heteroatom doping, defect engineering, and the construction of multinary composites. The design concept and superiorities of these strategies are thoroughly discussed. Following this, we systematically showcase the photocatalytic applications of g-C3N4/ZnIn2S4 heterojunctions, encompassing CO2 reduction, H2 evolution, pollutant degradation, H2O2 production, biomass conversion, photoelectrochemical sensors, and so forth. Last, we propose the challenges that lie ahead in future research endeavors. This comprehensive review is expected to provide an instructive guideline for rational design and applications of g-C3N4/ZnIn2S4 heterojunctions.

Abstract :

Herein, a versatile amorphous-to-crystalline transformation (ACT) strategy is described, to furnish various metals (Cu, Co, Ni, Cs, and Y) based atomically dispersed catalysts (ADCs) on thin holey 2D Al2O3. This approach, which involves adjusting reactant stoichiometry, enables the continuous modulation of particle size of ADCs at an atomical level, giving the ultrafine products as single atom, cluster, or nanoparticle catalysts. This synthesis method allows a straightforward analysis and comparison of the reactivity of the ADCs catalysts based on the dispersion of the active metal. In the case of Cu, the cluster catalyst 0.2-Cu/Al2O3 outperforms the single atom catalyst 0.1-Cu/Al2O3 and the nanoparticle catalyst 0.3-Cu/Al2O3 in the oxidation of refractory organic molecules, thanks to its superior electron transport and surface adsorption properties. These findings are well supported by the Density functional theory (DFT) calculations. Additionally, this method facilitates the preparation of atomic clusters with a very small size of 0.5-1 nm, composed of just a few atoms, as exemplified by Ni-based ADCs. The developed synthesis enriches the library of ADCs and demonstrates the potential of amorphous-to-crystalline transformation in creating advanced ultrasmall functional materials.

Abstract :

Overcoming the challenges of integrating disparate components in nanoarchitectures, this study introduces a straightforward strategy based on a mixed-valence coordination approach, creating an ordered ternary heterostructure integrated with ultrasmall homojunction. This singular ordered homojunction-heterostructure unites ultrathin 1D rutile TiO2 nanowires (NWs) and ultrathin anatase TiO2 NWs with 0D Prussian Blue Analogs (PBAs) nanoparticles (NPs), all exhibiting crystallographic oriented alignment with each other, forming a ternary mesocrystals. Experimental and theoretical insights disclose that the complex interplay between these dissimilar components is governed by a spontaneous lattice match effect, which not only optimizes but also directs the charge transfer, thereby enhancing both efficiency and stability. It also allows for tailoring the valence states of Fe within the PBA, fine-tuning of the composite's photochromic properties, and introducing abundant defect structures that foster strong interaction with oxygen molecules, enabling controllable color-switching dynamics. Consequently, the FeII1-xFeIIIx-PBA/TiO2 exhibits an optimized ternary structure of R-TiO2/A-TiO2/PBA, demonstrating exceptional photoelectronic properties, significantly enhancing photochromism and secure encryption capabilities. These insights establish a solid foundation for engineering sophisticated complex-ordered nanoarchitectures, advancing sustainable energy and environmental technologies.

Abstract :

Lattice oxygen (O-L) redox chemistry is a key to alleviating the energy and environmental crisis, but it faces challenges in activating the O-L while ensuring structural stability. We disclosed herein that engineering a heterogeneous interface between ultrathin oxide and amorphous carbon can attain the durable O-L redox chemistry without introducing catalytically impure sites. To this end, we proposed a green strategy to grow similar to 3.9 nm-thickness wrinkled delta-MnO2 nanosheets that are rich in defects and are vertically aligned on amorphous carbon spheres. Experiments and calculations reveal that the electrons can easily migrate from the amorphous carbon to MnO2 at the delta-MnO2@C heterointerface. The heterogeneous interfaces can not only regulate the Mn-O bond and create oxygen defects in delta-MnO2 but also introduce lattice oxygen with varying reactivities. Specifically, the delta-MnO2@C structure carries more activated lattice oxygen that contributes to the enhanced activity on catalytic oxidation of bioderived 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA), with a high FDCA formation rate of 1759 mu mol gcat(-1) h(-1) and a high selectivity of 95%. The heterogeneous interface of MnO2@C also brings inert lattice oxygen, so that it manifests high structural stability during the oxidation reactions. This work deepens the fundamental understandings in the engineering of lattice oxygen for durable lattice oxygen redox chemistry and showcases an effective interface technique in creating advanced catalysts for clean sustainable energy.

Abstract :

In this work, we exploited the synergy between homogeneous and heterogeneous catalysis for the efficient and selective activation of H2O2. The homogeneous catalyst contained a very trace amount of Fe2+ (0.26 ppm), which is lower than the international effluent discharge standard for Fe (0.50 ppm). The heterogeneous catalyst was composed of holey graphitic carbon nitride (g-C3N4) nanosheets carrying highly dispersed single atoms (Mn, Ni, or Cu). Mechanistic studies revealed that the strong interaction between single metal sites and H2O2 forms two adsorption configurations (HOO- and H(O-O)-), which trigger the generation of different reactive oxygen species (ROS). The heterogeneous Mn-C3N4 catalyst provided single Mn-N-3 sites that activated H2O2 to produce O-2 by forming HOO-Mn-N-3, while the adjacent Fe2+ quickly reduced the generated O-2 to O-center dot(2)-, which can efficiently remove organic pollutants and inactivate Escherichia coli under neutral conditions. The single-atom Mn-C3N4, in addition, provided photoactive electrons that drive the efficient cycling of the homogeneous Fe2+/Fe3+ catalyst (which is the rate-determining step) under very trace Fe2+ input. By coupling homogeneous and heterogeneous catalysis, an excellent and advanced oxidation process with potential for large-scale application is reported in this work; the findings also shed light on the theoretical aspects of the efficient and selective activation of H2O2 at the atomic level.

Abstract :

A facile gaseous CO2 mediated solid-to-solid transformation principle is adopted to insert additional CO32- anions into the thin single-crystal nanosheets of Bi2O2CO3, which is built of periodic arrays of intrinsic CO32- anions and (Bi2O2)(2+) layers. The additional CO32- anions create abundant defects. The Bi2O2CO3 nanosheets with rich interlayer CO32- exhibit superior electronic properties and charge transfer kinetics than the pristine single-crystal 2D Bi2O2CO3 and display enhanced catalytic activity in photocatalytic CO2 reduction reaction and the photocatalytic oxidative degradation of organic pollutants. This work thus illustrates interlayer engineering as a flexible means to build layered 2D materials with excellent properties.

General and Scalable Synthesis of Mesoporous 2D MZrO2 (M = Co, Mn, Ni, Cu, Fe) Nanocatalysts by Amorphous-to-Crystalline Transformation SCIE

Abstract&Keyword Cite Version(2)

Abstract :

In modern heterogeneous catalysis, it remains highly challenging to create stable, low-cost, mesoporous 2D photo-/electro-catalysts that carry atomically dispersed active sites. In this work, a general shape-preserving amorphous-to-crystalline transformation (ACT) strategy is developed to dope various transition metal (TM) heteroatoms in ZrO2, which enabled the scalable synthesis of TMs/oxide with a mesoporous 2D structure and rich defects. During the ACT process, the amorphous MZrO2 nanoparticles (M = Fe, Ni, Cu, Co, Mn) are deposited within a confined space created by the NaCl template, and they transform to crystalline 2D ACT-MZrO2 nanosheets in a shape-preserving manner. The interconnected crystalline ACT-MZrO2 nanoparticles thus inherit the same structure as the original MZrO2 precursor. Owing to its rich active sites on the surface and abundant oxygen vacancies (OVs), ACT-CoZrO2 gives superior performance in catalyzing the CO2-to-syngas conversion as demonstrated by experiments and theoretical calculations. The ACT chemistry opens a general route for the scalable synthesis of advanced catalysts with precise microstructure by reconciliating the control of crystalline morphologies and the dispersion of heteroatoms.

Abstract :

Flexible metal-organic framework (MOF) films are greatly desired for the separation of hazardous molecules and ions from wastewater. The current MOF films are usually horizontally deposited on the substrates, and thus restricted by brittleness, low exposure of surface area, as well as poor separation functions. Here, an organic-inorganic mixed substrate is firstly fabricated by growing hydroxyapatite (HA) nanowire arrays on the cellulose fiber (CF). Subsequently, MIL-100(Fe) nanocrystals are assembled on the surfaces of HA nanowire arrays through a layer-by-layer manner, leading to a unique vertical MOF film. The resulting vertical MOF films show competitive advantages over the horizontal counterparts: (i) they show excellent flexibility and they are tolerant to serious physical damage; (ii) they have multiple separation functions including ion exchange of HA, excellent adsorption of MOFs, and strong electrostatic interaction of CF; and (iii) the agglomeration of MIL-100(Fe) nanocrystals is effectively suppressed. Therefore, the average roughness, specific surface area, and average pore size of films are optimized. As a result, the vertical MOF films show universal separation of positively/ negatively-charged dyes and Pb2+ ion, with high removal rates of > 94 %. More appealing, the mixed pollutants in the complex wastewater can be one-step separated through the vertical MOF films, with high removal rates of > 96 %.

Abstract :

One hurdle in developing transition metal oxide (TMO) catalysts for aerobic oxidation reactions is their need for a low binding energy of the lattice oxygen (O-L) to create active O-L and a high O-L binding energy to maintain structural stability during catalysis. In this work, we prepared amorphous Zr-doped manganese oxide (amor-Zr:MnOx) catalysts carrying dual lattice oxygens that can address such conflicting objectives in catalyst development. In the aerobic oxidation of 5-(hydroxymethyl)furfural (HMF), the amor-Zr0.2MnOx catalyst gave 99% selectivity for 2,5-furandicarboxylic acid (FDCA) and a high FDCA formation rate of 3600 mu mol(FDCA) g(cat)(-1) h(-1) in 1 h. To the best of our knowledge, the aerobic oxidation performance of the amor-Zr0.2MnOx catalyst is superior to those of most Mn-based and related TMO-based catalysts under comparable conditions. Experimental and theoretical studies show that the O-L in amor-Zr: MnOx can be divided into two groups. One group includes the more stable O-L that strengthens the catalyst structure and prevents phase transition, while the other group includes the more reactive O-L that improves catalyst activity through the strong adsorption/activation of O-2 and helps regenerate O-L during catalysis.

Abstract :

Halide perovskites and derivatives have been used as emerging photocatalysts due to their unique optoelectronic and structural diversity. However, compared with the well-explored photophysical processes for light-driven more energetic carriers to trigger redox reactions, catalytic effects on the surface of halide perovskite or their derivatives for chemical transformations between reactive species are seldom addressed, which is equally important for improving the efficiency for halide perovskite-based photocatalysts. Here, we demonstrate that Cs3Bi2Br9 sites in the Cs3Bi2Br9/CdS heterojunction, not only participate in light-driven processes, but also play a vital role for the activation and conversion of key intermediates during C(sp3)-H bond transformation, via a more thermodynamically and kinetically favorable surface reaction pathway. Besides, various aromatic hydrocarbons can be effectively photocatalytic converted to corresponding aldehydes/ketones as major products. This work highlights the importance of surface catalysis mechanism in photocatalysis not only for halide perovskites but also for other semiconductors.
