摘要：

A highly selective defect-mediated photochemical CO2 conversion to CO over defective CeO2 nanorods under ambient conditions (CO2 400 ppm) is presented. The local strain and surface oxygen vacancies embedded in the defect-rich CeO2 are suggested to play a decisive role in mediating the photochemical CO2 conversion.
