Novel Cu2O cubes with exposed {110} facets have been prepared. When evaluated for the photocatalytic performances, the etched Cu2O manifest higher photocatalytic activity than that of the normal Cu2O cubes.
We developed a simple method to obtain the PdPtAu@Pd core@shell catalyst for methanol oxidation reaction. The PdPtAu@Pd exhibited superior photo-electrocatalytic behaviors, whose mass activity is 2.3 and 6.7 times higher than Pt/C and Pd/C.
