摘要
过渡金属氧化物MnO_(x)因优异的活性和低廉的价格被广泛应用于臭氧的催化分解。为了开发能在高湿度环境下长期稳定工作的锰基氧化物催化剂,总结了臭氧在锰基氧化物催化剂上湿气流中分解机理与催化剂失活机理,概括了可提升锰基氧化物催化剂抗水性的技术手段。针对未来应用需求,建议开发耐湿性能优异且环境友好的臭氧分解锰基氧化物催化剂。
Transition metal oxide MnO_(x) is widely used in catalytic decomposition of ozone because of its excellent activity and low price.In order to develop manganese-based oxide catalysts with stable catalysis capability in high humid condition for long time,the mechanism of ozone decomposition in humid air on manganese-based oxide catalysts was summarized,as well as the mechanism of deactivation of catalysts,the techniques to improve the water resistance of manganese-based oxide catalysts were concluded.In order to meet the future requirements of application,it was suggested to develop environmental-friendly manganese-based oxide catalysts for ozone decomposition with excellent water-resistance.
