Considering their outstanding cost-to-efficiency ratios, Cuprous oxide (Cu₂O) is emerging as an ideal photocathode. However, fast charge recombination and low resistance to photo-corrosion limit its practical applications. So, in this conference, we will introduce a graphitic carbon nitride (g-C₃N₄)/2D-Cu₂O nanowires (NWs) with core-shell heterojunction.
