Abstract:Altering the surface stoichiometry of semiconductor electrodes is known to affect the photoelectrochemical (PEC) response. To date, several reports have hinted at the influence of the surface Bi:V ratio on the solar water oxidation performance of BiVO4 photoanodes, but only a handful of strategies have been reported to afford to fine-tune such surface stoichiometry while a comprehensive understanding of an atomic level of the role of the surface termination remains elusive. Herein, we report a new methodology … Show more
