| titleOfInvention | Visible-light-driven photocatalyst, and preparation method and application thereof |
| abstract | A visible light catalyst and its preparation method and application, add hydrochloric acid solution into titanium tetrachloride, add sodium carbonate solution to pH9.0 after stiring, get amorphous titanium dioxide after suction filtration, washing; and (3) continuously adding hydrochloric acid until the pH value is 1.0, introducing nitrogen to discharge dissolved oxygen, adding an oxygen-free aqueous solution of sodium sulfide and ferrous sulfate, stirring, and placing the emulsion in a hydrothermal reaction kettle for reaction to obtain the nano ferrous sulfide/titanium dioxide composite material. The catalyst can react with formaldehyde and volatile organic compounds under the action of natural light and visible light to degrade the formaldehyde and the volatile organic compounds in the air. The catalyst has the advantages of simple preparation method, mild synthesis conditions, realization of catalytic reaction under visible light and natural light, wide wavelength response range and strong photocatalytic activity. |
