Preparation method of sulfide quantum dot modified graphene/titanium oxide nano microsphere photocatalytic material |
| abstract |
The invention discloses a preparation method of a sulfide quantum dot modified graphene/titanium oxide nano microsphere photocatalytic material, which is characterized in that a simple hydrothermal method and a heat treatment method are used for preparing flower-shaped graphene/titanium oxide nano microspheres, and on the basis, the flower-shaped graphene/titanium oxide nano microspheres and the sulfide quantum dots are prepared into the sulfide quantum dot modified graphene/titanium oxide nano microsphere photocatalytic material by an ultrasonic stirring method by utilizing the special structure and excellent performance of the sulfide quantum dots, so that a novel sewage treatment catalytic material which is easy to recycle, wide in spectral response range and high in catalytic activity is constructed. |
