Semihydrogenation of acetylene is an essential process in the ethylene industry for removing impurities and ensuring production polymer-grade ethylene. Atomically dispersed Cu catalysts have attracted significant attention due to their cost-effectiveness catalytic potential. However, inherently weak hydrogen dissociation ability results low activity, necessitating elevated reaction temperatures, which limit its practical applicability. To overcome this limitation, we design a Ru single-atom-decorated, fully exposed cluster catalyst (Ru1Cun/SiO2) that exhibits outstanding performance semihydrogenation acetylene, achieving 100% conversion with 98% selectivity at 170 °C. High-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), X-ray absorption spectroscopy (XAS), photoelectron (XPS) confirm atomic dispersion structural evolution clusters. H2-D2 exchange temperature-programmed desorption (TPD) experiments reveal modification significantly enhances while tuning adsorption. Density functional theory (DFT) calculations further demonstrate single atoms nanoclusters create synergistic interface markedly promotes activation lowers energy barrier rate-determining step. This study provides fundamental insights into rational atomically bimetallic offers new strategy efficient selective hydrogenation.

Abstract As a pivotal bio‐based building block, 2,5‐furandicarboxylic acid (FDCA) holds immense and broad application potential in the chemistry industry. Its polymeric derivative, polyethylene furandicarboxylate (PEF), emerges as an appealing alternative to conventional petroleum‐based terephthalate (PET). The electrochemical route for oxidizing 5‐hydroxymethylfurfural (HMF) into FDCA presents significant advantages over thermochemical processes, without requirements of high temperature, pressure, chemical oxidants, precious metal catalysts, featuring higher energy efficiency. Furthermore, electrosynthesis at anode can be synergistically integrated with selective reduction reactions cathode, enabling simultaneous production two desirable value‐added products further enhancing overall utilization This work reviews advancements electrocatalytic HMF (EHTF), encompassing catalyst design, reaction mechanisms, coupling strategies, reactor configurations. It also indicates challenges opportunities EHTF provides insights future development directions.
