Hematite an overview | ScienceDirect Topics
Doping hematite has been done to improve some of its intrinsic properties. Emphasis here is given on nonnoble metal dopants. Ti 4 + doping increases the donor concentration of hematite by 10fold, thereby facilitating an easier charge transport compared to bare hematite photoanodes [30]. Moreover, impedance measurements showed that Ti dopants ...
