▎ 摘  要

NOVELTY - Preparing derived titanium dioxide/reduced graphene oxide composite gas gel comprises adding Ti2CTxMXene into water, and ultrasonicating to obtain dispersion; adding graphene oxide to the dispersion, and ultrasonicating to obtain a mixed liquid; adding the mixed solution into a Teflon-lined stainless steel autoclave and reacting at high temperature, dialyzing obtained gel in a mixed solvent of ethanol and water, and freeze-drying. USE - The method is useful for preparing derived titanium dioxide/reduced graphene oxide composite gas gel used in radioactive wastewater treatment. The derived titanium dioxide the radioactive waste water gel obtained by adding uranium-containing radioactive waste water under the xenon lamp simulating sunlight condition, carrying out photo-catalytic reaction, realizing photo-catalytic reduction of hexavalent uranium in uranium-containing radioactive waste water.
