Promoting Photocatalytic CO₂ Methanation by the Construction of Cooperative Copper Dual-Active Sites

ACS Catalysis, Год журнала: 2024, Номер 14(7), С. 5275 - 5285

Опубликована: Март 25, 2024

Selective photocatalytic CO2 methanation provides an attractive avenue to address energy and environmental issues. However, impediments such as the sluggish adsorption activation of H2O molecules, along with unexpected intermediate desorption, greatly restrict activity selectivity methanation. To these issues, we devised a dual-active site catalyst comprising Cu single atoms (SAs) nanoclusters (NCs) supported on defective TiO2 (Cu1+NCs/BT). As result, remarkable CH4 98% yield 19.63 μmol gcat.–1 h–1 can be obtained over as-prepared Cu1+NCs/BT in pure water. Mechanistic studies reveal enhanced performance could ascribed synergistic effect sites, where SAs adsorb activate CO2, while NCs boost dissociation for *H coverage. Additionally, adjacent jointly stabilize *CO reduce barrier protonation, promoting multielectron transfer process.
