Summary: A non-acidic mesoporous silica-supported Pt catalyst was developed to produce biomass-derived 5-methylpyrrolidone under room temperature and atmospheric hydrogen. The suitable mesoporous structure created high dispersion of Pt species and accelerated the reaction processes. The isomerization of imine to enamine on the catalyst made this conversion easy under mild conditions.

Summary: The hydrogenation of polycyclic aromatic hydrocarbons (PAHs) using highly efficient and stable catalysts can effectively utilize coal tar and slurry oil for the production of fine chemicals and intermediate materials. In this study, Pt and Rh catalysts supported by Al2O3 were synthesized using strong electrostatic adsorption (SEA), which exhibited smaller particle sizes and higher dispersion compared to traditional catalysts synthesized by wet impregnation. The Pt/Al2O3-SEA catalyst showed higher catalytic activity for the hydrogenation of anthracene, and the hydrogenation routes were found to differ between the Pt/Al2O3 and Rh/Al2O3 catalysts. The Pt/Al2O3 catalyst resulted in the selective production of symmetrical octahydroanthracene (sym-OHA) with high selectivity and conversion, and demonstrated excellent stability for multiple cycles.

Summary: To achieve efficient hydrogen production at high current densities, this study develops a Mn-doped Ni2P/Fe2P electrocatalyst through a hydrothermal-phosphorization method. The electrocatalyst exhibits low overpotentials for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in alkaline seawater/freshwater electrolytes, as well as excellent stability even at high OER current densities. The efficient optimization of the electrocatalyst's electronic structure and the creation of active sites contribute to its high performance. This study provides a simple approach to fabricating non-noble electrocatalysts for freshwater/seawater splitting at high currents.

Summary: Decorated Pt/CeO2 catalysts with Zn species exhibit high efficiency and stability in the semi-hydrogenation of 1,4-butynediol. The Pt delta-Zn delta+ structure and reduced Pt surface density due to Zn decoration significantly impact the adsorption structures and bonding strength, resulting in favorable hydrogenation properties. The PtZn0.5/CeO2 catalyst achieves the highest 1,4-butenediol yield (85%) under mild conditions and maintains stability over long-term reactions (100 h). This study provides fundamental guidelines for designing high-performance Pt-based catalysts for selective hydrogenation of alkynols.

Summary: High-entropy alloys (HEAs) show remarkable catalytic performance in various reactions, but their synthesis with controlled structures remains a challenge. This study successfully prepared ultrasmall PtFeCoNiCu HEA nanoparticles supported on carbon nanotubes (CNTs) through a lithium naphthalenide-driven reduction method. The supported PtFeCoNiCu/CNT catalyst exhibited high catalytic activity, selectivity, low activation energy, and excellent stability in the hydrogenation reaction of maleic anhydride to succinic acid. Moreover, the mass-specific activity of Pt in this catalyst was much higher than that of Pt/CNT. This work provides strong support for HEAs as advanced heterogeneous catalysts and promotes further research and application in selective hydrogenation.

Summary: The catalytic hydrogenation of unsaturated bonds in petroleum resin is a promising way to improve its properties. However, the presence of sulfur compounds in petroleum resin presents a great challenge to hydrogenation catalysts. In this study, PdNi bimetallic catalysts were prepared and applied in the hydrogenation of DCPD petroleum resin, demonstrating higher sulfur tolerance compared to monometallic catalysts. The enhanced catalytic performance of the Pd1Ni1-MgAlO-HT catalyst can be attributed to small particle size, high dispersion of metal particles, and the synergy effect between Pd and Ni species. This research will guide the design of efficient sulfur tolerance catalysts for polymer hydrogenation derived from hydrotalcite-like precursors.
