NOVELTY - Preparing three-dimensional titanium carbide/ red hydrogel photocatalytic material with graphene as supporting frame involves mixing the titanium carbide solution and the graphene oxide solution. The obtained mixture is orderly added with red solution and sodium bisulfite. The mass ratio of titanium carbide and graphene oxide solution is 1-4:1. The mixture is stirred for 30-40 min. Nitrogen is then introduced to the reaction system at 70-80 degrees C for 10-15 minutes. The obtained mixture is heated for 8-10 hours. The obtained product is washed by water, removing he residual sodium bisulfite. USE - Method for preparing three-dimensional titanium carbide/ red hydrogel photocatalytic material with graphene as supporting frame for photo-catalytically degrading heavy metal ions. ADVANTAGE - The method enables to prepare three-dimensional titanium carbide/ red hydrogel photocatalytic material with graphene as supporting frame important practical value for degrading heavy metal ions in the water body, and is beneficial to the sustainable development of environment and energy.
