The MoS.sub.2@TiO.sub.2 hollow sphere heterostructures (MoS.sub.2@THS) were synthesized and used for photocatalytic reduction of U(VI) from wastewater under visible light. The optimum MoS.sub.2@THS-12 shows the highest photocatalytic reduction rate (irradiated for 80 min) with excellent recyclability and stability, which is approximately 4.1 times as much as the pure MoS.sub.2. The improved photocatalytic activity of MoS.sub.2@THS-12 is mainly due to the II-types heterojunction formed between MoS.sub.2 and THS. Meanwhile, the photogenerated electrons and superoxide radical are important active species in the photoreduction U(VI) process. The results provide an effective strategy for uranium resource utilization and pollution abatement.
