Abstract

An ultrastable Au nanocatalyst based on a heterostructured perovskite support with high surface area and uniform LaFeO₃ nanocoatings was successfully synthesized and tested for CO oxidation. Strikingly, small Au nanoparticles (4-6 nm) are obtained after calcination in air at 700 °C and under reaction conditions. The designed Au catalyst not only possessed extreme sintering resistance but also showed high catalytic activity and stability because of the strong interfacial interaction between Au and the heterostructured perovskite support.
