摘要
20世纪末以来,人们发现金在CO低温氧化中具有良好的催化活性,由此拉开了金催化研究的序幕。金催化有着重要的学术价值及广泛的应用前景。本文在简述了金催化的研究开发意义、商业价值及机理研究基础上,评述了近几年来金催化在一些有工业应用前景的化学反应中的国内外研究现状,重点对CO氧化反应、水煤气变换反应、烯烃加氢、醇和醛氧化反应、双氧水合成、碳氢键活化反应等进行了评述。还特别结合作者课题组在金催化羰化反应中的最新研究成果进行了深入讨论。若金催化剂能够大规模用于或部分替代其它贵金属所涉及的催化领域,将会产生一场历史性的变革。
The catalysis reactions by gold compounds has appeared as a powerful tool in synthesis.Research on catalysis with gold content has rapidly become a hot topic in chemistry.Gold is shows equally effective as both heterogeneous and homogeneous catalysts.In this review,we attempt to incorporate these two facts to demonstrate this new found and general efficacy of gold in reactions,especially in some important industrial chemical processes.The latest discoveries are placed within a historical context,but the main focus is to highlight the new catalytic possibilities that gold-catalyzed reactions currently offer synthetic chemist,in particular in CO oxidation,water gas shift reaction,hydrogenation,carbonylation,CH bond activation,H2O2 synthesis reaction and nucleophilic additions etc.Some aspects of reaction mechanism and applied engineering of these multiphase catalytic reactions have also been reviewed,with about 49 latest references.
