Synthesis of valence-mixed Cu phthalocyanine/ Graphene/g-C3N4 ultrathin heterojunctions as efficient photocatalysts for CO2 reduction

Although g-C3N4-based heterojunctions show promise for photocatalytic CO2 reduction, enhancing charge separation and creating sufficient catalytic sites remain challenges. In this study, valence-mixed CuPc/Graphene/g-C3N4 (HT-CuPc/G/UCN) ultrathin heterojunctions (~4.8 nm thickness)...
