Solar carbon dioxide (CO2) conversion is an emerging solution to meet the challenges of sustainable energy systems and environmental/climate concerns. However, construction isolated active sites not only influences catalytic activity but also limits understanding structure-catalyst relationship CO2 reduction. Herein, we develop a universal synthetic protocol fabricate different single-atom metal (e.g., Fe, Co, Ni, Zn, Cu, Mn, Ru) anchored on triazine-based covalent organic framework (SAS/Tr-COF) backbone with bridging structure metal-nitrogen-chlorine for high-performance Remarkably, as-synthesized Fe SAS/Tr-COF as representative catalyst achieved impressive CO generation rate high 980.3 μmol g-1 h-1 selectivity 96.4%, over approximately 26 times higher than that pristine Tr-COF under visible light irradiation. From X-ray absorption fine analysis density functional theory calculations, superior photocatalytic performance attributed synergic effect atomically dispersed host, decreasing reaction barriers formation *COOH intermediates promoting adsorption activation well desorption. This work affords rational design state-of-the-art catalysts at molecular level provides in-depth insights efficient conversion.

Photocatalytic CO2 conversion for hydrocarbon fuel production has been known as one of the most promising strategies achieving carbon neutrality. Yet, its efficiency remains unsatisfactory mainly due to severe charge-transfer resistance and slow charge kinetics. Herein, a tunable interfacial transfer on an oxygen-vacancies-modified bismuth molybdate nanoflower assembled by 2D nanosheets (BMOVs) bismuthene composite (Bi/BMOVs) is demonstrated photocatalytic conversion. Specifically, meticulous design Ohmic contact formed between BMOVs can allow modulation resistance. According density functional theory (DFT) simulations, it ascertained that such exceptional kinetics attributed built-in electric field (IEF) contact. As such, reduction performance optimized Bi/BMOVs (CO CH4 productions rate 169.93 4.65 µmol g-1 h-1 , respectively) ca. 10 times higher than pristine BMO rates 16.06 0.51 respectively). The reported in this work shed some important light highly efficient photocatalysts both energy environmental applications.
