Here, an enhanced Mie scattering effect of the well-documented porous BiVO4 photoanode is obtained with less effort by a simple annealing process, which significantly reduces the reflectivity to near zero. The great light absorbability increases the basic photocurrent density by 1.77 times. The selective oxidation of GLY over the BiVO4 photoanode results in a photocurrent density of 6.04 mA cm？2 and a DHA production rate of 325.2 mmol m？2 h？1 that exceeds all reported values. This work addresses the poor ability of nanostructured BiVO4 to harvest light, paving the way for further improvements in charge transport and transfer to realize highly efficient PEC conversion.
