▎ 摘　　要

NOVELTY - Preparing graphene hydrogel involves calcining titanium dioxide nanotubes in presence of inert gas, processing calcined material with acidic, alkaline or neutral aqueous solution, and then adding graphene oxide to processed material. The mixture is treated with reducing agent, and the obtained product is sonicated to obtain the desired product. USE - Method for preparing graphene hydrogel (claimed). ADVANTAGE - The method enables to prepare graphene hydrogel with good absorbing effect in an eco-friendly manner.
