A g-C3N4/WO3 photoanode with exceptional ability for photoelectrochemical water splitting†
Abstract
Herein, we report a photoanode of g-C3N4/WO3 heterojunctions with exceptional ability and stability for photoelectrochemical (PEC) water splitting which achieved a high photocurrent density of 1.92 mA cm−2 at +1.23 V versus (vs.) RHE which is about 2 times higher than that of the pristine WO3 photoanode (0.71 mA cm−2).
