Abstract

Abstract : To elucidate the factors affecting the catalytic properties of supported Au catalysts on the metal oxide support we investigated Au NPs deposited on crystallized mesoporous transition-metal oxides ( m -oxides: Co3 O4, NiO, and α-Fe2 O3 ) prepared using the nanocasting method. Abstract : To elucidate the factors affecting the catalytic properties of supported Au catalysts on the metal oxide support we investigated Au NPs deposited on crystallized mesoporous transition-metal oxides ( m -oxides: Co3 O4, NiO, and α-Fe2 O3 ) prepared using the nanocasting method. The metal–oxide interaction in Au/mesoporous oxides resulted in higher catalytic activity for converting methanol to CO2 as a full oxidation product than pure m -oxides. Au/ m -Fe2 O3 exhibited high activity and low selectivity for methyl formate as a partial oxidative coupling product. We correlate the change in activity and selectivity with the interface between the Au and m -oxides.
