Abstract ：
Palladium-based catalysts have been intensively investigated for the hydrogenation of nitroarenes due to their high activity. However, it remains a challenge to achieve high selectivity when reducing or halo groups are present. Herein, we propose a facet engineering strategy to regulate the activity and selectivity of Pd/TiO2 and a series of Pd/TiO2 catalysts with adjustable proportions of (101) and (001) facet of TiO2 were synthesized for the selective hydrogenation of nitroarenes. With increased percentage of (101) facet, better dispersed Pd species and more oxygen vacancies (OV) can be generated on the Pd/TiO2 catalyst, thereby providing increasing hydrogenation reaction centers with strongly adsorbed nitro groups. As a result, the Pd/TiO2 with dominant (101) facet and 0.1 wt% of Pd loading (Pd/TiO2-c) delivers an outstanding conversion (100 %) of m-chloronitrobenzene, high selectivity (96.8 %) toward m-chloroaniline, and excellent reusability. In situ characterizations and density functional theory (DFT) simulation reveal that the Pd/TiO2-c exhibits much stronger adsorption toward nitro groups than chlorine group, while the catalyst with more (001) facet shows similar adsorption capability toward these two groups. Thereby, nitro group is more preferentially adsorbed and hydrogenated during the reaction on Pd/TiO2-c, which explains the excellent selectivity. Remarkably, Pd/TiO2-c can also realize excellent conversion (100 %) and selectivity (> 96 %) toward other functional nitroarenes containing −F, –OH, –CHO, –COCH2- groups. This work highlights the facet engineering of supports to tune the physicochemical properties of loaded active metal and the adsorption behavior of reactants, and provides an effective strategy for the further development of efficient Pd-based catalysts for selective nitroarenes hydrogenation. © 2024

Abstract ：
Using the Sandmeyer mclhod with 3-chloro-2-mcthylaniline as the raw material and sodium nitrite as diazotization reagent, diazonium salts were obtained at low temperature and acid environ-ment. Then, copper-based catalysts were used to decompose diazonium salts under-different temperature conditions to obtain 2-chloro-6-bromotoluene. The optimal synthesis conditions are to dissolve the amine in 30% sulfuric acid (mass fraction), form the diazonium sali with a sulfuric acid Solution of sodium nitrite, use hydrobromic acid as the bromine source, copper powder as the catalyst, and decompose at 0 °C. Among them, the amount of acid used is 5 times that of the raw material, n(3-Chlo-ro-2-mcthylanilinc): n (sodium nitrite): n (copper): n (industrial hydrobromic acid): 1: 1. 2: 0. 1: 1. 2, and the yicld of 2-chloro-6-bromotoluene reaches 95%. © 2025 SINOPEC.

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 ：
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 ：
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 ：
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 ：
The catalytic dehydration of glycerol to acrolein offers a sustainable route for efficiently utilizing low-cost and renewable bioglycerol. This work deeply explores glycerol dehydration to acrolein over ZSM-5 zeolite catalysts with various pore structures and aluminum distributions. The results reveal that glycerol conversion is enhanced through the construction of a mesoporous structure and the increase in Br & oslash;nsted acid sites of the catalysts, but acrolein selectivity is not directly related to these factors. Further characterizations, density functional theory calculation, kinetic study, and reaction mechanism analysis demonstrate that the richest Alsingle sites in the zeolite framework and the least Alpair sites in the straight and sinusoidal channels can prevent the generated acrolein from adsorbing on adjacent Al sites. This allows acrolein to immediately escape from the catalyst surface, reducing side reactions and enhancing its selectivity. Therefore, the synergistic between the mesoporous structure and more Alsingle sites in the ZSM-5 zeolite framework promotes acrolein yield. Additionally, a descriptor phi, reflecting the amount of Alsingle sites and the external specific surface area of the ZSM-5 zeolite, is first proposed to more clearly elucidate the structure-performance relationship. This study provides a new perspective for understanding the mechanism of catalytic dehydration of glycerol to acrolein, guiding the development of highly efficient catalysts. It is significant for the sustainable development of the biodiesel and acrolein production industry.

Abstract ：
Aqueous-phase hydrogenation holds significance in achieving the large-scale green production of succinic acid, but the acidic reaction environment poses a considerable challenge in the design of highly active and stable catalysts. Herein, we report a spatial-confinement strategy to fabricate a Co-NPs@Co-N-C core-shell structured catalyst where Co nanoparticles (Co-NPs) are encapsulated tightly by nitrogen-doped graphitic carbon shells (NG), while Co single atoms (Co-SA) are distributed homogeneously on the shells, which exhibits remarkable efficiency and stability in the aqueous-phase hydrogenation of maleic acid for the production of succinic acid in an acidic medium. The catalyst achieves 100% conversion of maleic acid, more than 98% selectivity toward succinic acid, and high stability for seven cycles without significant deactivation. The combined characterizations and density functional theory (DFT) calculations further indicate that Co-NP and Co-SA can concurrently optimize the electronic structure of the NG and promote hydrogen dissociation on the surface of the carbon shells. These findings shed light on the unique function of Co-NP-NG-Co-SA composite sites on regulating the hydrogenation active centers and provide a guideline for the further development of highly efficient acid-resistant hydrogenation catalysts.
