Photoassisted capture of uranium provides a promising strategy for the sustainable utilization nuclear energy. Herein, we constructed Cu2O/CuO heterojunctions in situ by wet-etching method, showing ultrafast reaction kinetics and photocatalytic activity U(VI) reduction. In 8 ppm uranium-containing wastewater, exhibited remarkable extraction efficiency 94.6% within 10 min under irradiation, which exceeded most recently reported photocatalysts. The rate constant was 5.8-time larger than that pure Cu2O. A mechanism study indicated photogenerated electrons reduced CuO species created oxygen vacancy during photocatalysis process, strengthened binding UO22+. rapid electron transfer over heterojunction interfaces enhanced UO22+ strength formed accounted kinetics.
