Research Progress of Noble Metal Catalysts for Hydrogenation of Aromatic and Heteroaromatic Compounds
氢能作为零污染清洁能源,其储存与运输是制约大规模应用的关键.液态有机氢载体(LOHC)技术的核心是芳环及芳杂环化合物的加氢反应实现常温储氢,而贵金属催化剂性能直接决定该技术的应用效率.本文综述了钌(Ru)、铂(Pt)和钯(Pd)等贵金属催化剂在苯、甲苯等芳环及N-乙基咔唑、吲哚和喹啉等芳杂环化合物加氢中的研究进展.重点分析载体工程(介孔材料、碳基载体、金属氧化物)、单原子分散、双金属协同及氢溢流效应等策略对催化剂活性、选择性和稳定性的调控机制.这些研究通过原子级活性位点调控与载体功能化协同优化,提升LOHC体系储氢效率,为解决贵金属成本高、高温烧结等问题提供新思路,为氢能产业链的经济性和工业化应用奠定基础.
As a zero-pollution clean energy,hydrogen storage and transportation restrict its large-scale application.The core of liquid organic hydrogen carrier(LOHC)technology lies in hydrogenation of aromatic and heteroaromatic compounds,where noble metal catalysts play a decisive role in determining the application efficiency of this technology.This review summarizes the research progress of noble metal catalysts in hydrogenation of aromatic compounds(benzene,toluene)and heteroaromatic compounds(N-ethylcarbazole,indole,quinoline).It focuses on the regulatory mechanisms of support engineering(mesoporous materials,carbon-based supports,metal oxides),single-atom dispersion,bimetallic synergy,and hydrogen spillover effects on catalyst performance.These studies optimize hydrogen storage efficiency in LOHC systems through synergistic regulation of atomic-level active sites and support functionalization,providing new ideas to address high costs and high-temperature sintering of noble metals,and laying a foundation for the economic and industrial application of the hydrogen energy industry chain.
