Effect of Light and Electrode Polarization on BiVO4 and TiO2 Photoanodes for Glycerol Oxidation

In recent years, there has been a growing interest in the photoelectrochemical oxidation of glycerol to produce high-value products. Most studies have focused solely on the photocatalytic properties of the electrodes, overlooking their electrocatalytic properties and the different products obtained...
