Abstract

In studying the catalytic activities of SnO2-Sb2O4 (Sn:Sb=1:1) mixed oxides doped with Ga, In or Tl in the ammoxidation of propylene, a selectivity improvement was observed when the dopants Ga2O3 and Tl2O3 were used in low concentrations. At higher concentrations and for In2O3 the characteristics of the dopant prevail, disclosing that the admixed oxides are not evenly distributed in the bulk, but that the doping is rather confined to the surface layers of the catalyst.
