 Abstract: Polymeric carbon nitride (CN) is one of the most promising metal-free photocatalysts to alleviate energy crisis and environmental pollution. Loading cocatalysts is regarded as an effective way to improve the photocatalytic efficiency of CNs. However, commonly used noble metal cocatalysts limit their applications due to their rarity and high cost. Herein, we present the effective synthesis of single-atom copper modified CN via supramolecular preorganization with subsequent condensation, which provides effective charge transfer pathways by an “infused” delocalized state with variable-valence catalysis at the same time. The C-Cu-N2 single atom catalytic site can activate CO2 molecules and reduces energy barrier towards photocatalytic CO2 reduction. Excellent performance for photocatalytic CO2 reduction was found. This work thereby provides a general protocol of designing noble-metal free photocatalyst with infused metal centers towards a wide range of applications.
