CQDs hole transport layer enhanced photocatalytic performance of BiVO₄-based type II heterojunctions for water splitting

Key Points

• The research examines how the addition of carbon quantum dots (CQDs) as a hole transport layer can improve the photocatalytic efficiency of BiVO4 in water splitting applications.
• Implemented CQDs as a hole transport layer in BiVO4-based type II heterojunctions.
• Evaluated photocatalytic performance through water splitting experiments.
• The incorporation of CQDs significantly improved the photocatalytic performance of BiVO4.
• Enhanced charge separation rate reduced surface recombination, leading to increased efficiency in water splitting.
