Selective growth of palladium nanocrystals on the (100) facets of truncated octahedral Cu2O for UV plasmonic photocatalysis

Abstract

We report Pd-based UV plasmon-enhanced photocatalysis and its hot electron effect. The selective crystalline growth of Pd nanocrystals on the (100) facets of truncated octahedral Cu₂O was conducted and proved. The photocatalytic activities of Pd/Cu₂O at λ = 254 nm and at λ = 365 nm respectively had ca. 18- and 10-fold enhancements due to the hot electron effect.
