Abstract: Abstract Hematite is a promising photoanode material but limited by its large overpotential (0.5–0.6 V) toward water splitting. The slow kinetics and high density of trapping states are the main factors. The former could be improved… read more here.

DOI: 10.1016/j.jechem.2018.10.012
Abstract: Abstract Although there have been many reports of metal doping to ameliorate the drawbacks of hematite as the photoanode for water oxidation, most of them focused on monometallic doping, and only a few of them… read more here.
