Sol−Gel Concentration-Mediated WO3(002) Photoanodes: Synthesis and Photoelectrochemical Properties
Photoelectrochemical (PEC) water splitting is a promising technology for producing clean hydrogen, but the slow rate of the oxygen evolution reaction (OER) severely limits its overall efficiency. WO3 is a competitive n-type semiconductor for OER photoanodes owing to its low cost, good electron mobility, and suitable...
