Preparation and Application of Visible Light Driven Bi 2 O 3 -Cu 2 O Dual Photoelectrode Photocatalytic Fuel Cell
This study constructs a low-cost, visible-light-driven Bi₂O₃-Cu₂O dual-photoelectrode photocatalytic fuel cell that achieves efficient methylene blue degradation (96.46%) and power generation by replacing expensive noble metal cathodes with a Cu₂O photocathode and optimizing heterojunction carrier separation.
