Abstract
• Pt/CN photocatalyst with strong electronic metal–support interaction was fabricated. • Pt/CN exhibited efficient interfacial charge transfer and excellent performance in CO 2 methanation reaction. • Pt 2+ species play dual roles in the separation of photogenerated charges and the suppression of H 2 evolution reaction. • The heat input promotes the photogenerated electrons transport and induces high activity. Pt nanoparticle-loaded g-C 3 N 4 (Pt/CN) that consisted of integrating Pt 0 and Pt 2+ species was prepared for selectively reducing CO 2 to CH 4 with H 2 O by thermal coupled photocatalysis . A strong electronic metal-support interaction was constructed between Pt nanoparticles and the g-C 3 N 4 substrate, which limited the activity for CO evolution and improved the charge transfer from g-C 3 N 4 to Pt for selective CH 4 production. The formed Pt 2+ species in the Pt nanoparticles completely suppress the side reaction of H 2 production from reducing H 2 O. Moreover, a moderate heat input in the photocatalytic reaction facilitated the transfer of the photogenerated electrons from Pt nanoparticles to CO 2 , which further increased the photocatalytic activity for CH 4 evolution. As a result, a significant enhancement of CO 2 methanation performance (∼100 % selectivity, 14.8 μmol g −1 h −1 ) was realized on a 2 % Pt-loaded g-C 3 N 4 photocatalyst under low intensity light-emitting diode (420 nm, on the order of solar intensity) irradiation at 125 °C.
