Abstract

The use of bismuth vanadate (BiVO4) scheelite structures for converting solar energy into fuels and chemicals for fast growth in lab to industrial scale for large-area modules is a key challenge for further development. Herein, we demonstrate a new ultrasonic spray technique as a scalable and versatile coating technique for coating pristine and doped nanoporous BiVO4 thin film photoanodes directly on FTO-coated glass substrates for water splitting under visible irradiation. The successful Mo doping in BiVO4 lattice was confirmed by various characterization techniques such as XRD, Raman, EDS and XPS. The Mo:BiVO4 photoelectrode showed excellent performance with higher stability as compared to pristine BiVO4 samples.
