英文摘要A novel MnO2/g-C3N4heterojunction composite was synthesized via a simple in-situ redox reaction between KMnO4and MnSO4·H2O adsorbed on the surface of g-C3N4for the first time. MnO2featuring 2D δ-phase layered structure was intimately attached onto the surface of g-C3N4layers via [sbnd]C[sbnd]O[sbnd] bonding. Notably, the synthesized MnO2/g-C3N4photocatalyst showed substantially enhanced photocatalytic activity in the reduction of CO2than pure g-C3N4and MnO2. The highest CO production amount of 9.6 μmol g−1 has been obtained at an optimized loading amount of MnO2under 1 h irradiation of a 300 W Xe lamp. The incorporation of narrow band gap MnO2on the surface of g-C3N4enhanced its light harvesting ability. And the solid hetero-interface between MnO2and g-C3N4together with their well matched band structure was favorable for the separation of photo-induced carriers, consequently enhanced its photocatalytic activity. This novel 2D-2D MnO2/g-C3N4heterostructure is expected to have great potentials in CO2photoreduction. © 2017
