Four ozone decomposition catalysts were prepared and their catalytic reactivity were investigated.The ozone decomposition efficiency showed that even under a high humidity condition at relative humidity of 95%,the four variety of catalysts maintained high ozone decomposing performance for a long period of time.Especially,the RP catalyst had the best reactivity,the ozone decomposition efficiency after starting the reaction 20 hours still remained at 99.6%.
