Selective growth of Au nanograins on specific positions (tips, edges and facets) of Cu2O octahedrons to form Cu2O–Au hierarchical heterostructures

Abstract

This communication demonstrates a novel strategy for the selective growth of Au nanograins (AuNGs) on specific positions (tips, edges and facets) of Cu2O octahedrons to form Cu2O–Au hierarchical heterostructures. The surface energy distribution of the octahedrons generally follows the order of γ(facets) < γ(edges) < γ(tips) and leads to the preferential growth and evolution of the heterostructures. These novel Cu2O–Au hierarchical heterostructures show fascinating degradations of methylene blue (MB), due to the suppressed electron/hole recombination phenomena and the highly efficient light harvesting.
