Role of lithium doping on α-Fe2O3 photoanode for enhanced photoelectrochemical water oxidation

High-valent or equivalent foreign element doping could improve the charge separation of the hematite (α-Fe2O3) for enhancing the photoelectrochemical (PEC) water oxidation. However, the induced extra surface states would anodically shift the onset potential. This work reported a two-step hydrotherma...
