CO催化氧化催化剂改性研究进展

通过添加助剂(稀土金属和过渡金属)、选择合适载体(金属氧化物、分子筛及其他载体)及改进材料制备方法(采用微波替代传统加热方式等)三方面,综述了近年来对CO催化氧化催化剂进行改性的研究进展。非贵金属催化剂是催化领域的主流方向,采用不同的方法对非贵金属催化剂进行改性,提高CO催化氧化催化剂的催化活性、稳定性和实际应用是今后需要研究的主要内容。

Research progress on modification of catalytic oxidation catalyst for CO

The research progress is reviewed on modification of CO catalytic oxidation catalysts by adding auxiliaries(rare earth and transition metals),selecting suitable carriers(metal oxides,molecular sieves and other carriers) and improving the material preparation methods(using microwave instead of traditional heating methods,etc.) in recent years. Non-noble metal catalyst is the mainstream direction of catalysis research. Modification of non-noble metal catalysts by different methods to improve their catalytic activity,stability and practical application is the main research contents next.
