摘要：

A novel palladium supported on cerium, lanthanum, praseodymium and zirconium-pillared montmorillonite (MMT) catalysts are prepared and for the catalytic combustion of toluene, acetone and ethyl acetate. The order of catalytic activity is consistent with the different support: La-Zr/MMT approximate to Ce-Zr/MMT > Pr-Zr/MMT. X-ray diffraction (XRD) experiment revealed that the basal spacing of MMT enhanced from 0.97 nm to 1.73 nm after Zr-pillared treatment. After doping of Ce, La and Pr, the interlayer spacing increased to 1.94, 2.02 and 1.85 nm on Ce-Zr/MMT, La-Zr/MMT and Pr-Zr/MMT support. N-2 adsorption-desorption method and scanning electron microscopy (SEM) helped to understand the catalytic performance of these palladium supported and rare earth oxides doped MMT catalysts.
