A single-crystal BiVO4 photoanode with surface nanostructure was prepared using a low-cost and simple etching process, leading to higher photocurrent density and lower onset potential. This improvement can be attributed to the larger electrochemical active surface area and abundant oxygen vacancies on the surface.
A single-crystal BiVO4 photoanode with a surface nanostructure is prepared by a low-cost and simple etching process. As a result, the modified photoanode shows a higher photocurrent density and a lower onset potential, which is because of the larger electrochemical active surface area and abundant oxygen vacancies on the surface.
