“Waterproof” coats: Rh/Cr2O3 (core/shell) nanoparticles supported on a (Ga1−xZnx)(N1−xOx) solid solution are synthesized by an in situ photodeposition method. These nanoparticles (see picture) are used as a promoter for overall water splitting upon visible-light irradiation (λ>400 nm). Without the Cr2O3 shell water is formed from H2 and O2 in an undesired back reaction.
