摘　　要：氮氧化物(NOx)的直接催化分解是公认的消除NOx污染最有吸引力的方法。本文综述了近年来NOx催化分解领域深受关注的几类催化剂,包括贵金属、金属氧化物、钙钛矿及类钙钛矿型复合氧化物、离子交换的ZSM-5型分子筛、杂多化合物和水滑石类材料等六大类催化剂。介绍了相关的反应机理、反应动力学和催化性能等问题的国内外研究进展,概括了上述催化剂的优缺点,提出了未来的发展方向。Direct catalytic decomposition of NOx to N2 and O2 has been recognized as the most attractive method for eliminating pollution derived from NOx, since it does not require the addition of any reductant, without causing secondary pollution, and the process it concerned is simple and economical. In this paper, several interesting catalysts for NOx decomposition, including noble metals, metal oxides, perovskite （-like） mixed oxides, ion-exchanged ZSM-5 zeolites, heteropoly compounds and hydrotalcite （-like） compounds, are introduced concerning the research progress of reaction mechanism, reaction kinetics and catalytic activity. The advantages and disadvantages as well as future research trend of these catalysts are proposed.
