催化脱硝是催化研究领域中很重要的一部分。介绍了催化脱除氮氧化物（NOx）的几种方法：NOx直接催化分解法、NOx储存还原法（NSR）以及使用不同还原剂（碳烟尘、烃（HC））的选择性催化还原法（SCR）。讨论了NSR的反应原理和载体、贵金属、储存材料、SO2、H2O以及反应条件对整个催化作用的影响，同时论述了HC-SCR的两种反应机理，在机理讨论的基础上还分析了一些对HC-SCR反应活性有影响的因素：催化剂载体、金属负载量、焙烧温度、催化剂预处理方法、O2、还原剂、H2O和SO2。

The catalytic removal of nitrogen oxide（NOx） is one of the most importance in catalysis research. Some technologies of the catalytic removal of NOx such as direct decomposition of NOx, NOx storage-reduction（NSR） ,and selective catalytic reduction（SCR） using different reducing agents （diesel soot, or hydrocarbons） are described. The NSR reaction principle and the influence of the support, noble metals, storage materials, SO2, H20 and the reaction conditions are discussed. At the same time, two mechanisms of SCR of NOx by hydrocarbon （HC-SCR） are described. Based on the discussion of the reaction mecha- nism, some influence factors, such as catalyst support, metal loading, calcinations temperature, catalyst preparation method, O2, reducing agents, H2O and SO2, are analyzed.
