Cathodic shift and improved photocurrent performance of cost-effective Fe2O3 photoanodes

We successfully fabricated cost-effective and efficient pulse electrodeposited Fe2O3 photoanodes for PEC water splitting application. Surface modifications of Fe2O3 by oxygen evolution catalysts like cobalt phosphate (Co–Pi), a monoclinic BiVO4 or both showed cathodic/anodic shift in photocurrent with significantly improved photo-response.
