摘　　要：能源是现代社会赖以生存和发展的基础,乙醇作为一种优质的清洁能源,是很有应用前景的替代能源,它可由合成气催化转化制得。研发一种可以选择性生成乙醇并具有工业化应用前景的催化剂是该领域的研究热点。铑(Rh)基催化剂在合成乙醇、乙醛、乙酸的过程中因具有较好的乙醇选择性而备受关注。本文重点介绍了合成气催化转化制乙醇铑基催化剂的反应机理以及催化剂的活性中心、载体和助剂对催化活性、选择性的影响。Ethanol as a clean energy could be used as an alternate energy source.Ethanol can be obtained via catalytic conversion of syngas.Current researches focus on developing commercially attractive catalysts with high selectivity to ethanol.Rh-supported catalysts have been studied extensively as these catalysts produced ethanol,acetaldehyde and acetic acid with high selectivity.In this paper,the reaction mechanism of syngas conversion to ethanol over rhodium catalyst is introduced.The effects of active sites,support and promoter on the catalytic activity and product selectivity are summarized.
