中文摘要：
在原位合成的ZSM-5／堇青石整体式样品基础上制备了几种金属（Cu，ln或Ag）改性的ZSM-5／堇青石催化剂，并将其应用于稀燃发动机尾气的净化．结果表明，Cu-ZSM-5／堇青石催化性能最好，尾气中的三种主要污染物NOx，CO和HC可以同时得到净化．用微量（0．02％）贵金属（Pd，Rh或Ir）对Cu-ZSM-5／堇青石进一步改性，所得催化剂对CO的净化能力大大增强，保持高NOx转化率的温度窗口也大大加宽，因而该催化剂在稀燃汽车尾气净化方面具有潜在的应用前景．微量贵金属对Cu-ZSM-5／堇青石催化剂的改性作用也在文中进行了讨论．
英文摘要：
monolith. lean-burn By in situ synthesis, the ZSM-5 zeolite grew on the eordierite substrate and formed ZSM-5/cordierite Metal （Cu, In or Ag）-modified ZSM-5/cordierites were studied as catalysts to treat the exhaust of engine. Cu-ZSM-5/cordierite exhibited the best catalytic performance, and three main pollutants NOx, CO and HC in the exhaust could be purified simultaneously. By further modification with a trace amount （0.02%） a noble metal （Pd, Rh or Ir）, the purification ability of the catalysts for CO was greatly enhanced, and the temperature window of high NOx. conversion was greatly broadened. Bimetal modified ZSM-5/ cordierites were then regarded as promising catalysts in purifying the lean-burn exhaust. The modification effect of the trace noble metal on the catalytic performance of Cu-ZSM-5/cordierite was also discussed.
