摘　　要：制备了以活性炭和5A分子筛为载体的催化剂，考察了活性组分、相对湿度、活性组分含量以及空速等因素对其催化分解臭氧性能的影响，分析了臭氧在催化剂表面上的吸附和分解机理，得出以活性炭为载体的催化剂Mn—Ag-O／C具有良好的催化分解性能和较强的耐湿性能。Catalysts carried on active carbon and 5A molecular sieves were prepared, and effects of active composition, relative humidity, air speed and active composition content on catalytic activity for ozone decomposition were discussed. The mechanism of adsorption and decomposition for ozone on catalysts surface was analyzed. The results showed that the catalyst Mn-Ag-O/C carried on active carbon demonstrated favorable activity for ozone decomposition and well humidity-resistant performance.
