Abstract

This account describes the work of our group in the selective catalytic reduction of nitrogen oxides (NO ) with ammonia over heterogeneous photocatalysts (photo-SCR) in the past 16 years. We have found that the photo-SCR proceeds over heterogeneous photocatalysts using a gas flow reactor, elucidated the reaction mechanism under UV- and visible-light irradiation by spectroscopic and kinetic studies, and developed a highly active photo-SCR system by improving the photocatalyst material itself and the reaction system with several approaches based on the reaction mechanism.

摘要

本报告描述了我们小组在过去16年中在非均相光催化剂上用氨选择性催化还原氮氧化物(NO)(光催化选择性催化还原)方面的工作。我们发现,光催化选择性催化还原在使用气流反应器的非均相光催化剂上进行,通过光谱和动力学研究阐明了紫外光和可见光照射下的反应机理,并基于反应机理通过几种方法改进光催化剂材料本身和反应体系,开发了一种高活性的光催化选择性催化还原系统。
