Abstract A poly‐phosphamide (POP) with a band gap of 2.8 eV is used for the photochemical conversion CO 2 into CH 4 and chemical organo‐epoxides cyclic carbonates. The Tauc plot Mott Schottky analyses indicate conduction potential at −1.49 V (vs NHE), much more negative than multi‐electron reduction lifetime photo‐excited electron found ns. On photoirradiation 420 nm light, POP in presence triethanolamine or ascorbic acid can selectively convert (≈99%) yield 4.6 mmol g −1 . visible‐light irradiation, drop charge‐transfer resistance (R ct ) an enhancement cathodic current further confirm photon‐harvesting efficiency POP. In situ, FTIR study identifies adsorption to possible reaction intermediate, like *‐CO, *‐CH OH. also behaves as catalyst carbonates under solvent‐free conditions 98% yield. After light‐phase dark‐phase reactions, be successfully recycled least five times without structural degradation. Herein, acts bi‐functional, recyclable polymeric organic material essential feedstocks mild conditions.
