Abstract

The mix-faceted Cu₂O nanoparticles with tunable {111} and {100} facet ratios were successfully prepared by a facile method. In this experiment, the as-synthesised Cu₂O photocatalysts with different {111} and {100} facet ratios were more active than the sole {111} or {100} faceted Cu₂O. The optimised Cu₂O photocatalyst with 68% {100} facet displayed the highest visible light photocatalytic activity for hydrogen production, which was about 4.53 and 5.89 times as high as that of Cu₂O nanoparticles with the single (100) and (111) facets. Besides, possible photogenerated electrons and holes transfer mechanism of the mix-faceted Cu₂O was proposed in detail.
