纳米金催化剂上CO低（常）温氧化的研究

金历来被认为是催化惰性的，但近年来有关金催化剂的研究与开发引起人们的兴趣与关注。负载纳米金催化剂显示了良好的催化性能，尤其对一氧化碳氧化反应，能够在低（常）温下将CO氧化为CO₂。和其他CO氧化催化剂相比，金催化剂具有高的催化活性、稳定性和抗潮湿的性能，预示着更加广泛的应用前景。本文从制备方法、载体的性质、微粒粒径的大小、预处理、活性机理和催化反应机理等方面进行综合与评述。

Carbon Monoxide Low-temperature Oxidation over Nanosize Gold Catalyst

Gold has long been known as being catalytically inactive. However, more interest and attention have been concentrated on the research and development of gold catalysts in recent years. Gold catalysts have been shown good catalytic performances, especially for CO oxidation, and can be used to eliminate CO even below ambient temperature. Compared with other catalysts for CO oxidation, the nanosize gold catalysts have superior catalytic behaviors, such as high catalytic activity, high catalytic stability and high resistance to moisture, and show a continuously increasing and more extensive application prospects. In this review, the preparation factors such as preparation method, support, particle size, pretreatment condition were summarized. The activation and reaction mechanisms were discussed.
