The mix‐faceted Cu 2 O nanoparticles with tunable {111} and {100} facet ratios were successfully prepared by a facile method. In this experiment, the as‐synthesised Cu 2 O photocatalysts with different {111} and {100} facet ratios were more active than the sole {111} or {100} faceted Cu 2 O. The optimised Cu 2 O 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 Cu 2 O nanoparticles with the single (100) and (111) facets. Besides, possible photogenerated electrons and holes transfer mechanism of the mix‐faceted Cu 2 O was proposed in detail.
