摘要

氮氧化物（NO

）是大气中的一种主要污染物。采用具有菱沸石结构（CHA）的铜基分子筛作为催化剂，通过选择性催化还原（SCR）技术可有效去除N

。采用一种经济环保的制备方法，在不使用模板剂的条件下水热合成一种具有结构缺陷的低硅铝比CHA型分子筛（Phi，Si/Al=4.7）。结果表明，经Cu离子交换制备的Cu/Phi具有最丰富的表面酸性与孤立态Cu

，表现出较好的低温活性、较宽的工作温度窗口以及良好的水热稳定性。Na或Mg的存在降低了Cu/Phi的表面酸性及孤立态Cu

的含量，水热老化后的Na，Cu/Phi和Mg，Cu/Phi均呈现出不同程度的骨架坍塌，相应导致了催化剂失活。

Abstract

Nitrogen oxide (NO

) is one of the major air pollutants. Using a copper-based zeolite with a chabazite structure (CHA) as a catalyst

the selective catalytic reduction (SCR) technology can effectively remove NO

. This work introduces a low silica CHA type zeolite with structural defects (zeolite Phi

with Si/Al of 4.7). The zeolite Phi is synthesized through a hydrothermal method without adding any template

which is low-cost and environment-friendly. The Cu-exchanged Phi is abundant of surface acidity and isolated Cu

showing a superior low-temperature activity

a wide work temperature window and a good hydrothermal stability. The presence of Na or Mg decreases the surface acidity and isolated Cu

. The hydrothermally aged Na

Cu/Phi and Mg

Cu/Phi present different levels of framework collapse

which correspondingly induces catalyst deactivation.
