摘要
在汽车尾气模拟配气的条件下 ,用XRD和CO吸附技术研究了催化剂Pd/CeO2 中的Pd与CeO2 之间的SMSI对尾气的催化活性。结果发现高温还原能在催化剂Pd/CeO2 上形成SMSI 。
Under the simulated exhaust gas,the effect of SMSI between Pd and CeO 2 in catalyst Pd/CeO 2 on the calalylic activity for simulated exhaust gas were investigated by XRD,CO chemisorptions and the result is that HTR can give the SMSI of catalyst Pd/CeO 2 to rise and the SMSI can sharply improves the catalytic activity for simulated exhaust gas.
