Abstract :

Electrochemical biomass upgrading is a promising substitute for oxygen evolution reaction (OER) to generate valuable chemicals in conjunction with hydrogen generation. Pursuing highly efficient and durable electrocatalysts for significant concentration levels (≥ 50 mM) of biomass electrooxidation remains an enduring challenge. Herein, we introduce a robust Cu-supported CoFe Prussian blue analogue (CoFe PBA/CF) electrocatalyst, adept at facilitating high-concentration (50 mM) 5-hydroxymethylfurfural (HMF) oxidation into 2,5-furandicarboxylic acid (FDCA), achieving an exceptional HMF conversion (100%) with a notable FDCA yield of 98.4%. The influence of copper substrate and adsorption energy are therefore discussed. Impressively, the CoFe PBA/CF electrode sustains considerable durability in a continuous-flow electrochemical reactor designed for consecutive FDCA production, showcasing FDCA yields of 100/94% at flow rates of 0.4/0.8 mL·min-1 over 60 h’ uninterrupted electrolysis. This work provides a promising strategy to develop highly efficient and robust electrocatalysts for the consecutive production of high-value products coupled with green H2 production. © The Author(s) 2025.

Deciphering Ni0/Ni(OH)+ interfacial sites for deep hydrogenation of dicyclopentadiene resin SCIE
期刊论文 | 2025 , 512 | CHEMICAL ENGINEERING JOURNAL
Abstract&Keyword Cite Version(2)

Abstract :

Deep hydrogenation of dicyclopentadiene resin (DCPD resin) plays an important role in enhancing its performance and broadening its applications. However, designing suitable catalysts for promoting DCPD resin deep hydrogenation remains a challenge due to the high steric hindrance and abundant unsaturated bonds in DCPD resin, requiring strong binding to C=C double bonds. We herein propose a strategy for simultaneously constructing highly-dispersed Ni particles for hydrogen dissociation and interfacial Ni0/Ni(OH)+ sites for C=C adsorption by controlled reduction of Ni phyllosilicate (Ni PS). The catalyst, after reduction at 400 degrees C, demonstrated balanced ratio between Ni0 and interfacial Ni0/Ni(OH)+ sites, and achieved a hydrogenation degree of 99.8% (TOF: 68.8 h-1) while maintaining 99.3% efficiency after seven consecutive cycles. Through in-situ DRIFTS analysis and density functional theory (DFT) calculations, it is confirmed that the introduction of Ni0/Ni(OH)+ interfacial sites results in superior activity compared to pure Ni0 or unreduced PS due to optimized charge transfer and electronic configuration. This work not only establishes a simple and environmentally-friendly approach to design efficient catalysts for polymer hydrogenation, but also provides insights into the mechanism of unsaturated bond hydrogenation through the synergistic effects of Ni0 and Ni0/Ni(OH)+ interfacial sites.

Abstract&Keyword Cite Version(2)

Abstract :

The copper-based electrocatalysts feature attractive potentials of converting CO2 into multi-carbon (C2+) products, while the instability of Cu–O often induces the reduction of Cu+/Cu0 catalytic sites at the cathode and refrains the capability of stable electrolysis especially at high powers. In this work, we developed an Erbium (Er) oxide-modified Cu (Er–O–Cu) catalyst with enhanced covalency of Cu–O and more stable active sites. The f-p-d coupling strengthens the covalency of Cu–O, and the stability of Cu+ sites under electroreduction condition is critical for promoting the C–C coupling and improving the C2+ product selectivity. As a result, the Er–O–Cu sites exhibited a high Faradaic efficiency of C2+ products (FEC2+) of 86 % at 2200 mA cm−2, and a peak partial current density of |jC2+| of 1900 mA cm−2, comparable to the best reported values for the CO2-to-C2+ electroreduction. The CO2 electrolysis by the Er–O–Cu sites was further scaled up to 100 cm2 to achieve high-power (∼200 W) electrolysis with ethylene production rate of 16 mL min−1. © 2025 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences

Abstract :

Defect-engineered bimetallic oxides exhibit high potential for the electrolysis of small organic molecules. However, the ambiguity in the relationship between the defect density and electrocatalytic performance makes it challenging to control the final products of multi-step multi-electron reactions in such electrocatalytic systems. In this study, controllable kinetics reduction is used to maximize the oxygen vacancy density of a CuCo oxide nanosheet (CuCo2O4 NS), which is used to catalyze the glycerol electrooxidation reaction (GOR). The CuCo2O4-x NS with the highest oxygen-vacancy density (CuCo2O4-x-2) oxidizes C3 molecules to C1 molecules with selectivity of almost 100% and a Faradaic efficiency of approximate to 99%, showing the best oxidation performance among all the modified catalysts. Systems with multiple oxygen vacancies in close proximity to each other synergistically facilitate the cleavage of CC bonds. Density functional theory calculations confirm the ability of closely spaced oxygen vacancies to facilitate charge transfer between the catalyst and several key glycolic-acid (GCA) intermediates of the GOR process, thereby facilitating the decomposition of C2 intermediates to C1 molecules. This study reveals qualitatively in tuning the density of oxygen vacancies for altering the reaction pathway of GOR by the synergistic effects of spatial proximity of high-density oxygen vacancies. In this work, the qualitative tuning of oxygen-vacancy density on the reaction pathway of glycerol electrooxidation (GOR) is investigated, demonstrating that the synergistic effect induced by neighboring oxygen vacancies effectively promotes the CC bond cleavage of C2 intermediates to formate. This work offers insights for designing high-performance GOR electrocatalysts, facilitating the development of cost-effective and energy-saving chemical production technologies. image

Abstract :

Electrocatalytic oxidation as a promising route to produce value-added products from biomass-derived organics has received increasing attention in recent years. However, the efficient conversion of concentrated feedstock solutions with high selectivity and Faradaic efficiency (FE) remains challenging. Herein, we report a cation-defective Ni-based electrocatalyst derived from the surface reconstruction of the NiCo Prussian blue analogue (NiCo PBA) in alkaline media for the efficient oxidation of biomass-derived organics in a high concentration solution. Taking 5-hydroxymethylfurfural (HMF) as an example, the NiCo PBA can deliver a satisfactory catalytic performance in terms of high HMF conversion (97%), selectivity to 2,5-furandicarboxylic acid (98%), and FE (100%), even at a concentration as high as 100 mM. Theoretical calculations suggest that the cation defects not only promote the fast conversion of Ni(OH)(2) to electrochemically active NiOOH under anodic potential but also enhance the adsorption of HMF onto the active sites and accelerate the spontaneous chemical oxidation. This study provides deep insights into the structural evolution of PBA-based catalysts and reveals the pivotal factor that affects the performance of electrocatalytic oxidation, paving the way to further develop advanced electrocatalysts for efficient oxidation reactions with a high concentration.

Abstract :

Nanoscale defects can induce the effective modulation of carrier concentration, mobility, and phonon scattering to secure high thermoelectric performance in semiconductors. However, it is still limited to effectively controlling nanoscale defects in thermoelectric materials. Here, argon plasma bombardment is employed to introduce a large number of point defects and dislocations in microcrystalline SnSe powders, synthesized by a solvothermal method. After sintering these powders into polycrystalline bulk materials, bulk SnSe shows the ZT increasing by up to 66.7% (from 0.36 to 0.6 at 773 K). Through detailed micro/nanostructure characterizations and first-principles calculations, the underlying mechanism is elucidated for the evaluation of thermoelectric performance. This work provides a deep understanding of the mechanism of nanoscale defects in modulating thermoelectric performance and presents experimental evidence and experience for the design and synthesis of efficient thermoelectric materials, making significant contributions to future green energy technologies. Argon plasma is utilized to induce Sn vacancy defects in SnSe powders, enhancing ZT by 66.7% after sintering into bulk materials. Micro/nanostructure analyses and first-principles calculations elucidate the mechanism, advancing thermoelectric understanding. The findings offer insight into defect modulation for efficient thermoelectric materials, vital for future green energy technologies. image

Abstract :

C9 petroleum resin (C9PR) is a thermoplastic resin polymerized from the C9 fraction of ethylene cracking byproduct. After hydrogenation modification, it can be used to obtain high-value-added hydrogenated petroleum resin (HC9PR) with light color, high antioxidant stability and good compatibility. However, C9PR has high molecular weight, high steric hindrance and impurities such as sulfide in the raw materials which are easy to poison and deactivate the catalyst, making hydrogenation extremely difficult. Herein, in order to achieve simultaneous hydrogenation and desulfurization of C9PR, we have successfully prepared the amorphous NiP@γ-Al2O3catalyst by using chemical reduction method combined with ball milling method. The results showed that the catalyst has large specific surface area, high-content Niδ+ active species, high number of active sites and strong adsorption capacity for C==C bond. The obtained amorphous NiP@γ-Al2O3 catalyst showed an enhanced hydrogenation activity (hydrogenation degree of 98.35%) and desulfurization activity (sulfur content reduced from 122.80 μg/g to 8.00 μg/g) for C9PR hydrogenation, which is obviously superior to different crystalline nickel phosphide catalysts (the nickel phosphide was prepared by temperature programmed reduction method and loaded on γ-alumina carrier by ball milling). In addition, the amorphous NiP@γ -Al2O3 catalyst exhibited high hydrogenation degree after 100 h of continuous reaction, indicating that the catalyst had good stability. © 2024 Materials China.

Abstract :

Carbon adsorbents have been widely used to remove indoor volatile organic compounds (VOCs), however, the proliferation of bacteria on the carbon adsorbents may deteriorate the indoor air quality and thus pose a serious threat to human health. Herein, we report the synthesis of antibacterial porous carbon spheres (carbonized aminophenol-formaldehyde resin, CAF) with well-dispersed Cu species via an in situ incorporation of Cu2+ during the polymerization of 3-aminophenol-formaldehyde resin followed by a thermal carbonization and reduction process. Compared with CAF, the Cu/CAF-x nanocomposites with Cu loading show a much higher specific surface area (>700 m2 g−1 vs. 569 m2 g−1 for CAF). In addition, the pore size of Cu/CAF-x is ranging from 0.7 to 1.68 nm, which is exactly conducive to adsorb the toluene molecules. As a result, the toluene adsorption capacity is improved from 123.50 mg g−1 for CAF to >170 mg g−1 for Cu/CAF-x. More importantly, such adsorbents possess excellent antibacterial performance, the Cu/CAF-10 (10 wt% of Cu loading) with a concentration of 50 μg mL−1 can completely kill the E. coli within 30 min. Our work paves the way to the development of bifunctional adsorbents with both efficient VOCs adsorption and excellent antibacterial performance. © 2023

Abstract :

Water electrolysis for hydrogen production holds great promise as an energy conversion technology. The electrolysis process contains two necessary electrocatalytic reactions, one is the hydrogen evolution reaction (HER) at the cathode, and the other is the oxygen evolution reaction (OER) at the anode. In general, the kinetics of OER is much slower than that of HER, dominating the overall of performance electrolysis. As identified, the slow kinetics of catalytic OER is mainly resulted from multiple electron transfer steps, and the catalysts often undergo compositional, structural, and electronic changes during operation, leading to complicated dynamic reaction mechanisms which have not been fully understood. Obviously, this challenge presents formidable obstacles to the development of highly efficient OER electrocatalysts. To address the issue, it is crucial to unravel the origins of intrinsic OER activity and stability and elucidate the catalytic mechanisms across diverse catalyst materials. In this context, in-situ/operando characterization techniques would play a pivotal role in understanding the catalytic reaction mechanisms by enabling real-time monitoring of catalyst structures under operational conditions. These techniques can facilitate the identification of active sites for OER and provide essential insights into the types and quantities of key reaction intermediates. This comprehensive review explores various catalyst design and synthesis strategies aimed at enhancing the intrinsic OER activity and stability of catalysts and examines the application of advanced in-situ/operando techniques for probing catalyst mechanisms during the OER process. Furthermore, the imperative need for developing innovative in-situ/operando techniques, theoretical artificial intelligence and machine learning and conducting theoretical research to better understand catalyst structural evolution under conditions closely resembling practical OER working states is also deeply discussed. Those efforts should be able to lay the foundation for the improved fabrication of practical OER catalysts.
