Composition effects come to the surface

Metal oxide photoanodes are promising for solar-driven water oxidation, but a greater understanding of surfaces is required to minimize efficiency losses. New research shows that controlling terminal compositions of otherwise identical facets of complex oxides has a profound impact on photoelectrochemical function.
