摘要
VOCs的治理方法有多种,从耗能、反应速率、处理效率等各方面综合考虑,催化氧化法成为降解VOCs最有效的方法。由于Ce基催化剂具有独特的氧化还原特性和较强的氧储存能力而被频繁应用于VOCs催化氧化。综述了Ce基催化剂的制备方法;阐明了Ce基催化剂降解VOCs机理;概述了Ce基催化剂催化氧化VOCs的性能研究;探讨了催化剂目前存在的不足及未来的改进方向。
There are a variety of VOCs governance methods,from energy consumption,reaction rate,treatment efficiency and other aspects of comprehensive consideration,catalytic oxidation has become the most effective method to degrade VOCs.Ce-based catalysts are frequently used in VOCs catalytic oxidation due to their unique REDOX properties and strong oxygen storage capacity.The preparation methods of Ce-based catalysts were reviewed.The mechanism of VOCs degradation by Ce-based catalyst was elucidated.The performance of Ce-based catalysts for VOCs oxidation was summarized.The shortcomings of catalysts and the improvement direction in the future were discussed.
