摘要
详细概述了富氢气体中CO选择性氧化反应的贵金属和非贵金属催化剂,简要介绍了反应条件对催化剂活性的影响,指出控制催化剂的尺寸是金催化剂研究的重点,铂和其它非贵金属的抗CO2性和抗水性还有待进一步改善;通过便宜的添加剂、合适的制备方法和处理条件等手段来提高催化剂活性和选择性是有效的途径。
Noble and non-noble metal catalysts of CO selective oxidation in hydrogen-rich gas are summarized in detail. The effects of conditions on the activities of catalysts are introduced briefly. For gold catalysts, the dimension control is the focus of future research. The resistance to water and CO_2 of platinum and non-noble catalysts should be improved. Cheap additives, suitable preparation methods and conditions can effectively increase the activity and selectivity of catalysts.
