CuCe-Ox催化剂表面物种对CO催化氧化性能影响
Effect of surface species on the catalytic activity of CuCe-Ox catalyst in the CO catalytic oxidation
摘要
Abstract
In this paper, CuCe-Oxcomposite oxide catalysts are prepared by the co-precipitation method with different precipitants. The effect of the precipitants on its CO oxidation performance is investigated. The study shows that the catalyst with ammonia as the precipitant has the best CO oxidation activity, which is related to Cu-Ce-Ox catalysts with more Ce3+ and CuO species. In addition, the use of ammonia as a precipitant can promote the formation of CuO, which is the main active site for CO oxidation.关键词
