摘要：

Utilizing elemental doping and defect engineering are effective means to enhance the efficiency of g-C3N4 materials for photocatalytic removal of uranium. In this investigation, we synthesized a defective g-C3N4 photocatalyst co-decorated with K+ doping and cyano groups (KHCN) through a straightforward one-step alkali etching process. The alkali etching not only enhances the specific surface area to improve the adsorption of uranium by KHCN but also significantly accelerates the photocatalytic removal of uranium through the introduction of K+ and cyano groups. The KHCN can almost completely re...
