Graphitic carbon nitride-based materials for photocatalytic reduction of U(vi)

Abstract

The technology of photocatalytic reduction of U(VI) has wide application prospects in uranium recovery from seawater and in disposal of uranium waste because of its high efficiency, low cost, pollution-free nature and high selectivity. Graphitic carbon nitride (g-C3N4)-based materials have been regarded as ideal photocatalysts for the photocatalytic reduction of U(VI) (PCRU) because of their appropriate bandgap, unique two-dimensional (2D) layered structures, excellent physicochemical stability and outstanding optical properties; however, only few systematically reported on the visible light-driven catalytic reduction of U(VI), especially the process and mechanism of PCRU using graphitic carbon nitride-based materials. In this review, we systematically discuss the possible mechanism of PCRU. The PCRU using g-C3N4-based materials is reviewed in detail. On this basis, the g-C3N4-based materials widely employed in PCRU are reviewed. Then, the factors affecting PCRU with g-C3N4-based materials are addressed. Lastly, the current difficulties and future prospects of g-C3N4-based materials on PCRU are provided.
