| titleOfInvention | Magnetically-recyclable graphene/titanium dioxide photocatalytic composite material and preparation method thereof |
| abstract | The invention discloses a magnetically recyclable graphene/titanium dioxide photocatalytic composite material and a preparation method thereof. The method comprises the following specific steps: (1) preparing polyacrylic acid modified ferroferric oxide solution; (2) preparing a graphene/titanium dioxide photocatalytic material; then dispersing the mixture by using water; (3) preparing a polyethyleneimine modified graphene/titanium dioxide solution; (4) utilizing electrostatic self-assembly to incubate polyacrylic acid modified ferroferric oxide solution and polyethyleneimine modified graphene/titanium dioxide solution at normal temperature, and centrifuging to obtain a magnetic ferroferric oxide modified graphene/titanium dioxide composite material; (5) and (3) carrying out heat treatment on the composite material to obtain the magnetically-recyclable graphene/titanium dioxide photocatalytic composite material. The photocatalytic composite material prepared by the invention has high visible light photocatalytic degradation activity and large photocatalytic surface, and can realize effective recovery in a complex environment by regulating and controlling the self-assembly content of ferroferric oxide. |
