▎ 摘 要
NOVELTY - A titanium dioxide powder is added into acid solution for acidified processing, and an aqueous solution of graphene oxide is prepared in the titania solution. Organic solvent is added and stirred, to obtain slurry. Obtained slurry is cured, curing agent is added, and high molecular polymer is added and stirred. Cured slurry is concentrated, to obtain concentrated graphene oxide and titanium dioxide composite slurry. The prepared slurry is screen-printed on substrate in reducing gas, heated and reduced, to obtain graphene and titanium dioxide composite material. USE - Preparation of graphene and titanium dioxide composite material used for manufacturing dye-sensitized cell. ADVANTAGE - The graphene and titanium dioxide composite material is efficiently prepared with excellent photo-electro-catalytic electrode material, by simple method. DETAILED DESCRIPTION - A titanium dioxide powder is added into the acid solution for acidified processing, and an aqueous solution of graphene oxide is prepared in the titania solution. The solution is stirred, organic solvent is added, and then stirred, to obtain slurry. The obtained slurry is cured, curing agent is added and stirred, and high molecular polymer is added and stirred. The cured slurry is concentrated by distillation, to obtain concentrated graphene oxide and titanium dioxide composite slurry. The prepared slurry is screen-printed on a substrate in a reducing gas, heated and reduced, to obtain graphene and titanium dioxide composite material.
