| titleOfInvention | Method for preparing carbon-doped titanium oxide visible-light-driven photocatalyst by using waste as carbon source |
| abstract | The invention belongs to the field of preparation of titanium oxide materials, and particularly relates to a method for preparing a carbon-doped titanium oxide visible-light-driven photocatalyst by using waste as a carbon source. The method comprises the steps of taking sodium hydroxide and potassium hydroxide mixed alkali as a melting solvent, taking fern leaves and titanium dioxide which are agricultural and forestry wastes as raw materials, taking a hydrochloric acid solution (pH = 1) as an extracting agent, taking deionized water as a cleaning agent and a detergent, taking absolute ethyl alcohol as a detergent and a dry carrier, synthesizing a carbon precursor-titanate composite material under the conditions of normal pressure and low temperature of 180 ℃, and finally calcining at 450 ℃ to obtain the carbon-doped titanium oxide material with a porous structure. The product has high purity and stable chemical and physical properties. The carbon surface contains hydrophilic functional groups, the carbon-doped titanium oxide material has good water dispersibility, the photoresponse range can be expanded to a visible light wave band in sunlight, and the carbon-doped titanium oxide material has visible light catalytic activity. |
