Abstract

The invention discloses a preparation method and applications of a photocatalysis material prepared through adding of graphene. The preparation method comprises following steps: 1, indium and bismuthare dissolved in a nitric acid solution to obtain a mixed nitrate solution; 2, butyl titanate and isopropanol are mixed and stirred to obtain a mixed solution of butyl titanate and isopropyl; 3, a graphene aqueous solution, the mixed nitrate solution obtained in step 1, and deionized water are mixed and stirred to obtain a graphene mixed solution; 4, the graphene mixed solution prepared in the step 3 is mixed with the mixed solution of butyl titanate and isopropyl, and an obtained product is stirred, and is subjected to 2h of hydrolysis reaction at a reaction temperature of 60 to 70 DEG C; 5,the temperature is increased through heating to 95 to 100 DEG C, stirring is carried out, and reaction is carried out for 4h to form a viscous liquid; and 6, deionized water and isopropyl are added tothe viscous liquid, stirring is carried out, and when it is detected that the pH value becomes 7, stirring is stopped so ast o obtain a stock solution. The preparation method is simple and easy to operate, no ultraviolet light irradiation is needed, the antibacterial rate is high, and the organic matter decomposition performance is excellent.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a preparation method and application of a graphene-added photocatalytic material. Background technique [0002] The current photocatalytic materials are compounds based on nano-titanium ions and nano-indium ions, which can effectively convert light into electric charges. Through their photosynthesis, electron transitions allow oxygen atoms in water to form hydrogen peroxide to kill microorganisms. or decompose organic matter. Photocatalytic materials have strong substance decomposition ability and superhydrophilic effect. Using this function, photocatalytic materials can be used for air purification, water purification, decomposition of organic substances, anti-fogging and anti-fouling coatings. For example, the Chinese patent number is 201610013744.6, and the patent name is a material and its preparation method for ultraviolet photocatalytic removal of bromate in water....
