Synergistic Surface/Bulk Charge Modulation Enables Record-Level Photocurrent in Hematite Photoanodes without Co-Catalysts for Photoelectrochemical Water Splitting

Abstract Hematite (α-Fe2O3) photoanodes are limited by poor bulk conductivity and severe surface recombination, which hinder their photoelectrochemical (PEC) water-splitting activity. We demonstrate that a simple, rapid microwave-sintering (RMS) route simultaneously incorporates...

Boosting the Solar Water-Splitting Performance of a CuO Photocathode via Synergetic Interfacial Hole Extraction and Surface Electron Collection

Abstract P-type cupric oxide (CuO) is a promising photocathode material for solar hydrogen production, whereas its practical application is severely limited by constrained photoelectrochemical (PEC) performance and poor photostability. Herein, an integrated NiO/CuO/CuS photocatho...
