摘要:
Photocatalytic reduction of soluble hexavalent uranium to insoluble tetravalent uranium is a promising strategy for uranium-containing wastewater treatment, while this method generally requires anaerobic conditions and/or the addition of sacrificial agents. Obviously, providing anaerobic environment and sacrificial agent will not only increase the cost but also causes secondary pollution. Thus, efficient removal of U(VI) by photocatalytic techniques under air atmosphere without sacrificial agents is an urgent task and great challenge. In this w...
