NOVELTY - Preparing graphene/titanium dioxide composite flexible photocatalyst film involves dispersing graphene oxide in water to obtain 0.5 mg/mL graphene oxide dispersion solution, and dispersing 0.003-0.019 g titanium dioxide in 10 mL graphene oxide dispersion to obtain graphene/titanium dioxide dispersion. The graphene/titanium dioxide dispersion is suction-filtered on the suction filter to obtain graphene/titanium dioxide composite membrane to obtain graphene/titanium dioxide composite membrane. Graphene/titanium dioxide composite membrane is naturally dried and reduced to obtain graphene/titanium dioxide composite flexible photocatalyst film. USE - Method for preparing graphene/titanium dioxide composite flexible photocatalyst film. ADVANTAGE - The method enables to prepare graphene/titanium dioxide composite flexible photocatalyst film in simple manner which is easy to recycle the filter method to prepare desired film, and product has high degradation efficiency to the organic pollutant.
