Photodeposited Cu 2 O on BiVO 4 to Achieve a S-Scheme Heterojunction for Boosting Photocatalytic Water Purification

. Systematic characterization confirmed that the S-scheme charge transfer pathway significantly increased the generation of oxygen species and greatly promoted the overall photocatalytic activity. Moreover, the photocatalyst demonstrated excellent stability and recyclability, maintaining its activity without noticeable loss over multiple cycles, highlighting its strong potential for practical application. This work offers valuable insights into regulating photogenerated carrier transfer for enhanced water purification.
