The photocatalytic conversion of CO₂ into high-value chemicals is an ideal pathway to adjust the energy structure and reduce greenhouse gas emissions. In this work, we reported a facile synthetic strategy of new photocatalyst (ZnFe₂O₄/FeP-CTFs), where ZnFe₂O₄ nanoparticles (NPs) was in situ growth on iron porphyrin covalent triazine-based frameworks (FeP-CTFs) via one-pot ionothermal method. Such strategy can effectively prevent ZnFe₂O₄ from agglomerating and blocking the pore structure of CTFs. Notably, a series of experiments demonstrated that anchoring sites of FeP-CTFs can effectively promote the crystal-plane ratio of high catalytic performance, in the assistance of Ru(bpy)₃²⁺, promoting higher photocatalytic CO₂ reduction activity (178 μmol h^-1 g^-1 for CO) of the as-prepared ZnFe₂O₄/FeP-CTFs under visible light compared with pure ZnFe₂O₄, FeP-CTFs, and their physical mixtures. A combination of experimental measurements and density functional theory calculation reveals that the strong interactions between ZnFe₂O₄ NPs and FeP-CTFs support can facilitate the charge separation of photogenerated carriers and thereby benefit to photocatalytic CO₂ reduction.
