Electrospun Mo-doped BiVO4 photoanode on a transparent conductive substrate for solar water oxidation

• BiVO4 nanofibers are prepared on a FTO substrate by an electrospinning method.
• Photocurrents of electrospun BiVO4 photoanodes are improved by Mo doping.
• Hot pressed BiVO4 nanofibers shows enhanced charge separation efficiency.

Molybdenum-doped porous bismuth vanadate (BiVO4) nanostructures were successfully synthesized on a fluorine-doped tin oxide (FTO) substrate by a simple electrospinning technique. These nanostructures were used as the photoanode for solar water oxidation. Post hot-pressing treatment was crucial in improving the photocurrents of electrospun BiVO4 by contributing to their adhesion on the substrate and for charge separation.
