Pt nanoparticles with tunable size are prepared on the entire surface of facet‐engineered Cu 2 WS 4 decahedral photocatalyst via a kinetic‐controlled chemical reduction process. The {101} facets of the photocatalyst which featured photo‐oxidation, are successfully activated for photoreduction by Pt. The resulting photocatalyst shows an activity nine times higher compared to that of the only {001}‐facets activated catalyst obtained by a conventional in situ photodeposition route.
