▎ 摘  要

NOVELTY - Preparing two-dimensional photocatalytic-photo thermal composition material, comprises (i) dissolving graphene oxide in water, stirring the mixed solution in an ice bath to obtain a graphene oxide dispersion liquid, (ii) adding pyrrole monomer dropwise into graphene oxide dispersion liquid, stirring uniformly in an ice bath to obtain a reaction solution, and reacting the reaction solution in a reaction kettle to obtain a reduced graphene oxide pyrrole hydrogel, and (iii) dissolving the oxidant in water to form an oxidant solution, mixing the reduced graphene oxide pyrrole/hydrogel in the oxidant solution, reacting at 0-10℃ for 6-24 hours to obtain the reaction product, and cleaning the reaction product reduced graphene oxide pyrrole hydrogel. USE - The 2D/2D photocatalytic-photo thermal composition material is used for photo catalysis and water treatment (claimed). ADVANTAGE - The material has excellent photo-catalytic performance, expanded light absorption range, high photo generated vector mobility, and good stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a 2D/2D photocatalytic-photo thermal composition material, comprising a graphene oxide layer, and a poly pyrrole sheet layer formed on the graphene oxide layer.
