A versatile photochemical route is reported to access conformal metal oxide nanocoatings including Cr2O3, Al2O3, ZnO and In2O3 on semiconductor substrates. The Cr2O3 nanocoating can enhance the photoelectrochemical performance of GaN nanowires on a p-n junction Si photoelectrode, which exhibits a benchmark half-cell solar to hydrogen efficiency of 11.8%.
