摘要

Asymmetric oxygen vacancies Bi–O–Ce, as CO2 adsorption/activation sites in the on Ce0.9Bi0.1O2−δ, are associated with photothermal coupling reaction system to rapidly break the thermodynamic equilibrium at low pressure, achieving the selectivity of 100% and highly-efficient CO2 conversion to DMC (3.13 mmol∙g−1) with CH3OH.
