Boosting Charge Transfer of Fe Doping BiVO4/CoOx for Photoelectrochemical Water Splitting
Source abstract
Abstract
Charge separation efficiency is the main obstacle to limiting the photoelectrochemical (PEC) water-splitting performance of bismuth vanadate (BiVO 4 ) photoanodes. Herein, we report a convenient and efficient strategy for Fe doping into BiVO 4 and hybrid CoO x OECs to obtain a Fe-BiVO 4 /CoO x photoanode. The resulting photoanode exhibits 4.0 mA/cm 2 photocurrent density as well as a high charge transfer (74.4%)/separation efficiency (71.2%) at 1.23 V vs reversible hydrogen electrode (RHE) under AM 1.5 G illumination. The synergistic effect of Fe doping and CoO x OEC loading can dramatically boost the electrical conductivity and carrier density of BiVO 4 . This work provides effective experimental data for improving the PEC performance of BiVO 4 .
