Template-Free Synthesis of Hematite Photoanodes with Nanostructured ATO Conductive Underlayer for PEC Water Splitting

摘要: Hematite is a promising semiconductor candidate for PEC water splitting. However, hematite far well short of the theoretical value solar-to-fuel conversion efficiency because fast recombination photogenerated carriers. To address this limitation, facile template-free preparation photoanode with nanostructured ATO (antimony-doped tin oxide) conductive underlayer served as scaffold to transport electron was developed decrease opportunities Furthermore, constructed could also increase light absorption and number carriers, resulting in better performance hematite.
