Enhanced mid-visible light absorption and long-lived charge carriers in an electronically and structurally integrated BiVO 4 –TiO 2 photoanode for efficient artificial photosynthesis applications

BiVO 4 –TiO 2 films with abundant heterojunctions were produced using the SILAR process. The synergy between BiVO 4 QDs and TiO 2 leads to long-lived charge carriers, significantly enhancing photocatalytic efficiency.
