Abstract
The invention provides a TiO2-loaded nitrogen-doped graphene sponge preparation method and the application thereof, and belongs to the technical field of functional materials. According to the preparation method, a titanium-containing precursor is added in an ethanol dispersion liquid containing oxidized grapheme, and then the deionized water is slowly added into the ethanol dispersion liquid. The ethanol dispersion liquid is stirring evenly to obtain a mixed solution and the mixed solution is subjected to the hydrothermal reaction at 180 to 240 DEG C for 12 to 48 hours. After that, the solution is taken to be freeze-dried and shaped at -80 to -75 DEG C, and the high-purity nitrogen-containing gas is led into the solution in a vacuum tube-type furnace. The solution is heated to be roasted at 400 to 800 DEG C for 3 to 12 hours to obtain a three-dimensional porous nitrogen-doped graphene sponge containing 5 to 10% of TiO2. The preparation method is simple in process, and a large amount of gases containing formaldehyde or phenyl compounds can be absorbed by the sponge. Meanwhile, the gases containing formaldehyde or phenyl compounds can be degraded through the photocatalysis process under the irradiation effect of an ultraviolet lamp. Therefore, the adsorption saturation phenomenon is avoided, and the adsorption and the degradation are conducted at the same time till the end of the complete adsorption process. As a result, the purpose of efficiently and rapidly purifying the air is realized.
