摘要：

SnOx/Al2O3 catalysts were prepared by the sol-gel method using as starting reactants aluminium-tri-s-butoxide and (i) tetrabutyltin, (ii) tin tetrachloride and (iii) tin tetra-t-amyloxide. The gel derived catalysts show acidities of 0.72, 1.08 and 1.05 mu mol NH3/m(2) and BET areas of 91, 112 and 189 m(2)/g. The activity and selectivity pattern for isopropanol decomposition were found to depend strongly on the tin precursor used.
