1. A catalyst comprising:
- a substrate;
an intermediate layer having a partial monoatomic thickness or a monoatomic thickness and comprising MOx wherein MOx is selected from the transition metal oxides consisting of TiO2, ZrO2, CoOx (x=1-1.5), ZnO, and MnOx (x=1 to
4), the intermediate layer deposited on the substrate; and
a catalyst layer comprising a platinum group metal, the catalyst layer deposited on the metal oxide intermediate layer;
wherein the catalyst exhibits at least 95% selectivity for propene and further wherein the catalyst exhibits at least a 70% propane conversion.
