Preparation and Application of Porous Material Supported Gold Catalysts

This review outlines recent development of preparation, characterization and application of microporous material and mesoporous material supported gold catalysts. The selection of the microporous supports or mesoporous supports (unmodified oxides, microporous molecular sieves, mesoporous oxides, mesoporous molecular sieves and mesoporous carbon materials), the latest preparation methods of porous material supported gold catalysts (deposition-precipitation, sol-gel method, in situ/one-step method and chemical vapor deposition) and characterizations, as well as catalytic performance (carbon monoxide low-temperature oxidation, direct synthesis of hydrogen peroxide from hydrogen and oxygen, direct propylene epoxidation in the presence of hydrogen and oxygen and selective oxidation of organic compounds) are summarized. Meanwhile, the problem, as well as the research and development direction of porous material supported gold catalysts is presented.Contents
