More solar power thanks to titanium

Earth-abundant, cheap metals are promising photocatalytic electrode materials in artificial photosynthesis. A team of Chinese scientists now reports that a thin layer of titania beneath hematite nanorods can boost the performance of the photoanode. As outlined in their report in the journal Angewandte Chemie, the nanostructured electrode benefits from two separate effects. This design combining nanostructure with chemical doping may be exemplary for improved “green” photocatalytic systems.
