Modulating the coordination microenvironment of uranyl compounds to enhance photocatalytic CO2 reduction

Abstract

Rationalizing the use of depleted uranium resources has always been of great interest. Herein, we have obtained two actinide compounds by regulating the ratio of each component in the crystal growth process. By modulating the coordination microenvironment of uranyl, the actinide compounds exhibited significant differences in photocatalytic CO₂ reduction performance. The photocatalytic CO₂ reduction by UCu2 exhibited excellent reactivity, and the CO generation rate reached 481.6 μmol g⁻¹ h⁻¹. This study provides a reference and support for the rational application of depleted uranium resources and the application of coordinated polymers in the field of photocatalytic CO₂ reduction.
