| Abstract: | 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. |
