在反应釜压力0.15Mpa，气体置换时间30min，初始检测5min及到达样品表面的光强为0.1mw/cm²条件下，将表面光催化剂含量为0.4g每平方米的涂层放置在特定当氧化物含量的密闭光催化反应釜中进行60min的光催化反应，检测对氮氧化物的消除率变化。结果显示，60分钟对氮氧化物的去除率为12.3%。

The pressure of the reactor is 0.15Mpa, the gas replacement time is 30min, the initial detection is 5min and the light intensity reaching the sample surface is 0.1mw/cm ² Under the conditions, the coating with a surface photocatalyst content of 0.4g per square meter was placed in a closed photocatalyst reactor with a specific oxide content for 60 minutes to detect the change of the elimination rate of nitrogen oxides. The results show that the removal rate of nitrogen oxides in 60 minutes is 12.3%.
