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 :
Alkaline water electrolysis is one of the most prospective technologies for large-scale production of green hydrogen. Nevertheless, current porous membranes face the problem of weak ion transport or poor gas barrier performance. Here, we demonstrate a facile yet massive two-step casting and phase separation strategy to design a thin, asymmetric pore-structure modulated composite membrane for efficient, safe, and industrial-grade alkaline water electrolysis. The prepared composite membrane shows better electrolytic performance (1.71 V at 1 A cm-2) and stability (working for 6352 h). In addition, an industrial-grade electrolyzer equipped with composite membranes exhibits higher hydrogen production efficiency (1.03 Nm3h-1), H2 purity (99.9%), and faster dynamic response (less than 20 min) compared to mainstream commercial membranes. Ultimately, we propose a semi-empirical model based on the operational characteristics of an electrolyzer equipped with composite membranes and predicting its matching behavior with dynamic renewable energy sources. This work explores the viability of manufacturing high-performance alkaline water electrolysis membranes for green hydrogen production under industrial conditions.

Abstract :
Polyethylene oxide (PEO)-based electrolytes are essential to advance all-solid-state lithium batteries (ASSLBs) with high safety/energy density due to their inherent flexibility and scalability. However, the inefficient Li+ transport in PEO often leads to poor rate performance and diminished stability of the ASSLBs. The regulation of intermolecular H-bonds is regarded as one of the most effective approaches to enable efficient Li+ transport, while the practical performances are hindered by the electrochemical instability of free H-bond donors and the constrained mobility of highly ordered H-bonding structures. To overcome these challenges, we develop a surface-confined disordered H-bond system with stable donor-acceptor interactions to construct a loosened chain segments/ions arrangement in the bulk phase of PEO-based electrolytes, realizing the crystallization inhibition of PEO, weak coordination of Li+ and entrapment of anions, which are conducive to efficient Li+ transport and stable Li+ deposition. The rationally designed LiFePO4-based ASSLB demonstrates a long cycle-life of over 400 cycles at 1.0 C and 65 degrees C with a capacity retention rate of 87.5 %, surpassing most of the currently reported polymer-based ASSLBs. This work highlights the importance of confined disordered H-bonds on Li+ transport in an all-solid-state battery system, paving the way for the future design of polymer-based ASSLBs.

Abstract :
In order to gain insight into the influence of SiO2 support particle size on the vacuum residue (VR) slurry-phase hydrocracking performance of Fe-based catalysts, a series of FeZn/SiO2 catalysts with varying SiO2 particle sizes were prepared. Characterization results show that the surface area and pore volume of the FeZn/SiO2 catalysts increase with the reduction of SiO2 particle sizes. The metals Fe and Zn species on FeZn/SiO2-S catalyst are more readily reducible via H2-TPR analysis. Notably, FeZn/SiO2-S catalyst presents higher metal dispersion and a greater degree of sulfurization compared to the other catalysts by XRD and XPS. Hydrocracking results demonstrate that the FeZn/SiO2-S catalyst achieves the lowest coke and gas yields (11.9 wt% and 0.4 wt%), respectively, and the highest VR conversion among these catalysts. The superior performance of the FeZn/SiO2-S catalyst in VR slurry-phase hydrocracking is ascribed to its enhanced hydrogenation activity, deriving from the higher dispersion and sulfurization of metals species. This suppresses the aggregation of polycyclic aromatic hydrocarbons in VR and the over-cracking of intermediate products. Additionally, the increased mesopore associated with smaller SiO2 particles facilitates to the diffusion of large VR molecules, further promoting the hydrocracking reaction.

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 :
Diffusion behavior of catalyst pores plays a crucial influence in polymer heterogeneous hydrogenation reactions. However, experimental methods on how to accurately measure the diffusion coefficient of polymer molecules are still lacking. Herein, we develop an in-situ infrared-based method combined with mathematical models to accurately obtain the diffusion coefficients of polymers and investigate the effect of pore size on the diffusion and hydrogenation performance. Taking dicyclopentadiene resin as the model polymer, the results show that the selected Pd/Al2O3 catalyst with a pore size of 14.7 nm possesses an apparent diffusion coefficient of 3.83 x 10-15 m2/s and exhibits the best catalytic hydrogenation activity with a hydrogenation degree of 98.4%. This study provides a universal method for measuring the diffusion coefficients of polymer molecules, which holds significant guiding importance for the further development of more efficient polymer hydrogenation catalysts.

Abstract :
Elucidating the microstructure of hard carbon is essential for uncovering the sodium storage mechanism and constructing state-of-the-art hard carbon anodes for sodium-ion batteries. Guided by an understanding of the crystallization process and inverse materials design principles, we design hard carbon anodes with different local fragments to understand the correlation between the microstructure of hard carbon and sodium storage behavior from the commercialization perspective. The sodiation transformation of hard carbon from slope- to plateau-type is realized via a series of local structure rearrangements, including tuning of the interlayer distance, average crystallite width of graphitic domains, and defect density. We found that the increase in plateau capacity is mainly related to the transition from the critical interlayer distance to the average crystallite width of graphitic domain control, and is limited by the closed pore volume of hard carbon. During sodiation, the formation of NaF and Na2O in the slope region, as well as Na2O2 and NaO2 in the plateau region, is always accompanied by the production of Na2CO3. This work provides insights into understanding the sodium storage behavior in hard carbon anodes and defines general structural design principles for transitioning from slope-type to plateau-type hard carbon.

Abstract :
In recent years, studies focusing on the conversion of renewable lignin-derived oxygenates (LDOs) have emphasized their potential as alternatives to fossil-based products. However, LDOs, existing as complex aromatic mixtures with diverse oxygen-containing functional groups, pose a challenge as they cannot be easily separated via distillation for direct utilization. A promising solution to this challenge lies in the efficient removal of oxygen-containing functional groups from LDOs through hydrodeoxygenation (HDO), aiming to yield biomass products with singular components. However, the high dissociation energy of the carbon-oxygen bond, coupled with its similarity to the hydrogenation energy of the benzene ring, creates a competition between deoxygenation and benzene ring hydrogenation. Considering hydrogen consumption and lignin properties, the preference is directed towards generating aromatic hydrocarbons rather than saturated components. Thus, the goal is to selectively remove oxygen-containing functional groups while preserving the benzene ring structure. Studies on LDOs conversion have indicated that the design of active components and optimization of reaction conditions play pivotal roles in achieving selective deoxygenation, but a summary of the correlation between these factors and the reaction mechanism is lacking. This review addresses this gap in knowledge by firstly summarizing the various reaction pathways for HDO of LDOs. It explores the impact of catalyst design strategies, including morphology modulation, elemental doping, and surface modification, on the adsorption-desorption dynamics between reactants and catalysts. Secondly, we delve into the application of advanced techniques such as spectroscopic techniques and computational modeling, aiding in uncovering the true active sites in HDO reactions and understanding the interaction of reactive reactants with catalyst surface-interfaces. Additionally, fundamental insights into selective deoxygenation obtained through these techniques are highlighted. Finally, we outline the challenges that lie ahead in the design of highly active and selective HDO catalysts. These challenges include the development of detection tools for reactive species with high activity at low concentrations, the study of reaction medium-catalyst interactions, and the development of theoretical models that more closely approximate real reaction situations. Addressing these challenges will pave the way for the development of efficient and selective HDO catalysts, (c) 2024 Institute of Process Engineering, Chinese Academy of Sciences.
