摘要

WO3/ZrO2 mixed oxides supported on various porous silica were prepared. For the mesoporous silica, SBA-15 was found to retain the crystalline structure better than MCM-41 after loading W/Zr mixed oxides. Tungstated zirconia is mainly dispersed into the mesoporous channels of SBA-15, which causes the dramatical decrease in the surface area and pore volume. All the mesoporous siliceous materials supported solid acid samples showed strong acidity. The SBA-15 supported WO3/ZrO2 materials promoted with Pt were highly efficient in catalyzing the isomerization of n-pentane with a high selectivity of isopentane. SBA-15 with 1 %Pt/20%WO3/ 40%ZrO2 gave the highest catalytic activity.
