Enhanced Surface Kinetics and Charge Transfer of BiVO 4 Photoanodes by Rh 2 O 3 Cocatalyst Loading for Improved Solar Water Oxidation

A Rh O /BiVO composite photoanode exhibits enhanced surface reaction kinetics and charge transfer efficiency, enabling a photocurrent density of ca. 3.5 mA/cm at 1.23 V (vs. RHE), which is about 3.89 times higher than that of the pristine BiVO , with a lower onset potential of 0.29 V (vs. RHE)....
