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

摘要

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 = 254 nm and at = 365 nm respectively had ca. 18- and 10-fold enhancements due to the hot electron effect.
