NOVELTY - Preparing molybdenum disulfide (MoS2)/reduced graphene oxide nanosheets involves adding graphene oxide and phosphomolybdic acid (H3PMo12O40) to deionized water, stirring and performing the first ultrasound, then adding the sulfur source, stirring and performing the second ultrasound to obtain the reaction mixture. The reaction mixture is transferred to a teflon-lined stainless steel autoclave, reacted at 140-230 degrees C for 24 hours, and then naturally cooled to room temperature. The mixture is washed with water and dried overnight at 55-75 degrees C to obtain MoS2/reduced graphene oxide nanosheets. USE - Method for preparing MoS2/reduced graphene oxide nanosheets used for treating radioactive wastewater. ADVANTAGE - The method enables to prepare MoS2/reduced graphene oxide nanosheets, that can simultaneously selectively adsorb and photocatalyze and reduce uranium ions (U(VI)) under simulated sunlight, and reduced graphene oxide can be used not only as a substrate for growing MoS2, but also as an electron acceptor and transporter to improve charge separation, hence greatly improving the photocatalytic reduction ability of U(VI) extraction.
