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.

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 ：
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 ：
The heterogeneous selective hydrogenation of nitrile butadiene rubber (NBR) is an efficient method to generate high value-added hydrogenated NBR. Nevertheless, the inherent large molecular size and high spatial hindrance of polymers lead to poor activity and metal loss. Herein, we report a simple support ammonia pretreatment strategy for the synthesis of efficient N-doped Pd catalyst and applied for the NBR hydrogenation. The results reveal that N doping enhances electron transfer from the support to Pd more effectively than oxygen-rich vacancy support, thereby substantially enhancing the electron cloud density and stability of the Pd sites. The formation of more electron-rich Pd sites not only significantly enhances the adsorption-activation ability of C=C and H2, but also lowers the apparent activation energy of the reaction. As a result, the Pd/N-TiO2-R demonstrates best activity with a hydrogenation degree (HD) of 98 % and a TOF value of 335 h-1, significantly higher than that of Pd/TiO2-R (HD=83 %, 282 h-1) and Pd/TiO2 (HD=74 %, 204 h-1). This strategy will provide new inspiration to improve the activity and stability of Pd/TiO2 catalysts for the hydrogenation of unsaturated polymers.

Abstract ：
The electrocatalytic carbon dioxide or carbon monoxide reduction reaction (CO2RR or CORR) features a sustainable method for reducing carbon emissions and producing value-added chemicals. However, the generation of C3 products with higher energy density and market values, such as n-propanol, remains highly challenging, which is attributed to the unclear formation mechanism of C3+ versus C2 products. In this work, by the Tafel slope analysis, electrolyte pH correlation exploration, and the kinetic analysis of CO partial pressure fitting, it is identified that both n-propanol and C2 products share the same rate-determining step, which is the coupling of two C1 intermediates via the derivation of the Butler-Volmer equation. In addition, inspired by the mechanistic study, it is proposed that a high OH & horbar; concentration and a water-limited environment are beneficial for promoting the subsequent *C2-*C1 coupling to n-propanol. At 5.0 m [OH-], the partial current density of producing n-propanol (jn-propanol) reached 45 mA cm-2, which is 35 and 1.3 times higher than that at 0.01 m [OH-] and 1.0 m [OH-], respectively. This study provides a comprehensive kinetic analysis of n-propanol production and suggests opportunities for designing new catalytic systems for promoting the C3 production. A comprehensive kinetic analysis is conducted using the Butler-Volmer equation, including Tafel slopes, pH dependence, and the theoretical current density of n-propanol versus CO partial pressure, revealing *CO dimerization is the common rate-limiting step for both n-propanol and C2 products. A potential strategy is then used to promote the CO electroreduction performance to n-propanol. 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 ：
Pure-halide reduced-dimensional perovskites, featuring large exciton binding energy and tunable bandgap, show great potential for high-efficiency deep-blue perovskite light-emitting diodes (PeLEDs). However, their efficiency, particularly in the low n-value phase domain ("n" represents the number of octahedral sheets), lags behind analogous perovskite emitters. Herein, it is demonstrated that the vibration of edge-dangling octahedra in the low n-value phase activates notorious exciton-phonon (EP) coupling, thereby deteriorating efficiency. To address this issue, an approach is reported to manage edge-state lattices by introducing tris(4-fluorophenyl) phosphine (TFP) ligands. Attributed to the large steric hindrance of TFP ligands and their strong binding affinity for edge-dangling octahedra, the edged-octahedral tilting reconstruction can effectively suppress lattice vibration and inhibit EP coupling. This strategy yields deep-blue emitting film with a spectral linewidth of 21 nm and a photoluminescence quantum yield of 85% at low excitation densities. The resulting PeLEDs achieve deep-blue emission at 469 nm, with a maximum luminance of 2,428 cd m-2 and a maximum external quantum efficiency of 10.4%, marking them among the most efficient deep-blue PeLEDs reported. The strategy also showcases universality for higher n-value reduced-dimensional perovskites. It is believed that the observation, along with the edge-state management strategy, lays the groundwork for further advancements in reduced-dimensional perovskite optoelectronic devices.

Abstract ：
Microfluidic synthesis has emerged as a promising method for synthesizing metal-organic frameworks (MOFs). It overcomes the limitations of the traditional solvothermal method to regulate the structure and function of the MOFs. This study synthesized various MOFs with different structures and functions by controlling the reaction time and the ratio of metal ions to organic ligands through microfluidics and investigated their CO2 adsorption properties. The results showed that the microfluidic synthesized defective and hierarchical pore MOF-808 improved the adsorption performance of CO2 by nearly 110% and 30%, respectively, compared with solvothermal synthesized MOF-808.

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.

Abstract ：
Electrochemical glycerol oxidation features an attractive approach of converting bulk chemicals into high-value products such as glyceric acid. Nonetheless, to date, the major product selectivity has mostly been limited as low-value C-1 products such as formate, CO, and CO2, due to the fast cleavage of carbon-carbon (C-C) bonds during electro-oxidation. Herein, the study develops an atomically ordered Ni3Sn intermetallic compound catalyst, in which Sn atoms with low carbon-binding and high oxygen-binding capability allow to tune the adsorption of glycerol oxidation intermediates from multi-valent carbon binding to mono-valent carbon binding, as well as enhance *OH binding and subsequent nucleophilic attack. The Ni3Sn electrocatalyst exhibits one of the highest glycerol-to-glyceric acid performances, including a high glycerol conversion rate (1199 mu mol h(-1)) and glyceric acid selectivity (62 +/- 3%), a long electrochemical stability of > 150 h, and the capability of direct conversion of crude glycerol (85% purity) into glyceric acid. The work features the rational design of highly ordered catalytic sites for tailoring intermediate binding and reaction pathways, thereby facilitating the efficient production of high-value chemical products.
