摘要
氮氧化物是大气主要污染物之一,严重危害生态环境和人类健康。选择催化还原在富氧条件下能够高选择性的消除氮氧化物。氢气选择催化还原氮氧化物(H_2-SCR)因低温高活性备受关注。综述H_2-SCR研究中活性中间物种的研究进展,概述红外谱图中不同活性物种的吸收谱峰,对活性物种形式及所处位置进行总结和分类。
Nitrogen oxide(NOx)is one of the main pollutants in atmosphere,it seriously endangers ecological environment and human health.Selective catalytic reduction(SCR)is a technology that can selectively eliminate NOx in presence of excess oxygen.H 2-SCR has attracted much attention due to its high activity at low temperature.This paper reviews the research progress of different kinds of active intermediate species and outlines the adsorption band of different active species in IR spectra.The form and site of active intermediate species are summarized and classified with an emphasis.
