| titleOfInvention | Preparation method of photocatalyst and application of photocatalyst in reduction of chromium-containing wastewater |
| abstract | The invention provides a preparation method of a photocatalyst and application thereof in reduction of chromium-containing wastewater. The photocatalyst adopts fluorine nitrogen codope titanium dioxide/graphene composite material, and the fluorine nitrogen codope titanium dioxide/graphene composite material comprises the following components in percentage by weight: 1-10% of graphene, 80-98.8% of titanium dioxide, 0.1-5% of fluorine and 0.1-5% of nitrogen; the invention has the following beneficial effects: the titanium dioxide material codoped with fluorine and nitrogen improves the utilization of visible light, has certain reducing capability to hexavalent chromium under the visible light (lambda is more than 420nm), and the titanium dioxide basically has no response under the visible light. |
