Herein, we designed a sheet-like nanoporous covalent organic framework (TFP-DM COF) based nanomaterial, which was formedviaan easy solvothermal synthetic method. The as-synthesized material was characterizedviaFTIR spectroscopy, PXRD, UV-Vis, N(2)adsorption-desorption studies, TEM and FESEM techniques. We demonstrated the photocatalytic reduction of CO(2)into HCOOH and HCHO using the as-synthesized COF as the active photocatalyst and water as a green solvent as well as sacrificial electron source under atmospheric pressure. It was observed that the formaldehyde production rate was 36-fold higher than the formic acid production rate under white LED light irradiation. The catalyst showed good yields for both the products, HCOOH (0.019 mole) and HCHO (0.47 mole), even under sunlight irradiation. In addition, the COF material exhibited sufficient reusability without noticeable catalyst deactivation, which suggested the material to be a promising heterogeneous photocatalyst for commercial use in the CO(2)reduction reaction under green reaction conditions.
