Abstract

The extraction of uranium (VI) from uranium solutions is an attractive means in the context of increasing demand for uranium resources. Multiple photocatalysis can convert uranyl ions to UO2 precipitation by adjusting the valence of uranium species, which makes it one of the effective means of uranium extraction. In this paper, LDHS@TCN composites were prepared by in-situ growth method, and the II-scheme heterojunction photocatalyst was successfully constructed. The LDHS@TCN composites has photo-assisted uranium reduction ability, and the photo-assisted uranium extraction reaches 1719.12 mg g⁻¹. In addition, XPS and DFT calculations were used to verify the formation mechanism of II-scheme heterojunction and the photoelectron transfer pathway during the reduction of U(VI) to U(IV).
