光催化尾气降解复合材料研发与应用

Research and Application of Photocatalytic Composite Material for Exhaust Gas Degradation

本文基于光触媒材料反应原理,自主研发了光催化尾气降解复合材料;同时结合收费站高交通量、高尾气排放量等特殊使用条件,以及水泥路面结构形式,优选载体材料,将光催化复合材料负载于路表,打造尾气降解路面。同时,依托收费站尾气降解路面试验段实施,对光催化尾气降解路面实施效果进行了评价。结果表明,收费站光催化尾气降解路面综合降解效果达到50%以上,且基本前10min即可使尾气得到充分降解,具有显著的节能环保效果。

In this paper,based on the principle of photocatalyst reaction,autocatalytic degradation of photocatalytic compositematerials; at the same time with the toll station high traffic,high exhaust emissions and other special conditions,andthe cement pavement structure,the preferred carrier material,the photocatalytic composite load On the road surface,tobuild exhaust degradation road. At the same time,relying on toll station exhaust test section of the road to the degradation ofphotocatalytic degradation of the road to evaluate the effect of the road. The results show that the comprehensive degradationefficiency of photocatalytic tail gas on road surface of toll booths reaches more than 50%,and the exhaust gas can be fullydegraded in the first 10 minutes,which has significant energy saving and environmental protection effects.
