Interface-Engineering-Induced Reactive Hydrogen Supply in the Dual-Plasmon Heterojunction for Efficient CO 2 -to-CH 4 Photosynthesis

Artificial photosynthesis is considered an ideal technology to achieve the “dual-carbon” goals. However, sluggish H2O/CO2 activation and carriers’ severe recombination impede photocatalytic CO2 reduction reaction. Herein, this work innovatively proposes an “interfacial H2O dissociation” strategy on a MoN/Mo2N (MN) dual-plasmon heterojunction for achieving interface structure-dependent active *H generation in the CO2 photoreduction process. The formation of MN heterojunctions with a low lattice mismatch diminished interfacial mass transfer obstruction and promoted charge carriers’ separation efficiency, triggering a fast H2O dissociation reaction for proton *H generation with a decreased longitudinal relaxation…
