本文综述了微孔材料和介孔材料负载型金催化剂的制备、表征与应用研究的最新进展。从多孔载体的选择(氧化物、微孔分子筛、介孔氧化物、介孔分子筛和介孔碳材料)、金的最新负载方法(沉积-沉淀法、溶胶-凝胶法、原位法/一步法和化学气相沉积法)与表征及其催化性能(一氧化碳低温氧化、氢气/氧气直接合成过氧化氢、直接合成环氧丙烷和有机物的选择性氧化)等方面详尽地评述了微孔材料和介孔材料负载型金催化剂研究概况。同时,提出了多孔材料负载金催化剂存在的一些问题,并展望了其研究和发展的方向。 This review summarizes recent progress in preparation, characterization and application of supported gold catalysts for microporous and mesoporous materials. From the selection of porous supports (oxides, microporous molecular sieves, mesoporous oxides, mesoporous mesoporous and mesoporous carbon materials), the latest loading methods of gold (deposition-precipitation, sol-gel, in situ / Methods and chemical vapor deposition) and characterization and its catalytic properties (low temperature oxidation of carbon monoxide, direct hydrogen / oxygen synthesis of hydrogen peroxide, direct synthesis of propylene oxide and selective oxidation of organic matter, etc.) detailed reviews of microporous materials and intermediates Research Progress on Au Supported Metal Catalysts for Pore Materials. At the same time, some problems existed in porous materials supported gold catalysts were put forward, and their research and development directions were prospected.
