VOC (volatile organic compound) removing material for solution and preparation method of VOC removing material

Abstract

The invention provides a VOC (volatile organic compound) removing material for a solution and a preparation method of the VOC removing material. The method comprises the following steps: S1, slowly adding butyl titanate into absolute ethyl alcohol according to a ratio of 1:(4-6.5); S2, adding concentrated sulfuric acid to obtain a solution A; S3, adding TEOS (tetraethyl orthosilicate) into absolute ethyl alcohol according to a ratio of 1:(3-7.5), and conducting stirring to obtain a solution B; S4, adding the solution B into the solution A, conducting stirring for 2-2.5 hours, adding water, continuously conducting stirring for 4-4.5 hours, and conducting reacting at high temperature; S5, baking the mixture obtained in the step S4 to obtain a titanium dioxide and silicon dioxide mixture; S6, adding magnesium powder into the mixture, and conducting calcining; S7, carrying out ultrasonic oscillation on the mixture in an HCl solution, conducting filtering, and baking the obtained powder to obtain catalytic powder; and S8, adding a surfactant into the catalytic powder, adding water, and fully conducting mixing. The preparation method provided by the invention can be used for preparing the aqueous solution VOC removal material with extremely high photocatalytic utilization rate, and can be suitable for removing VOC in an aqueous solution state.

Description

technical field [0001] The invention relates to the technical field of VOC treatment, in particular to a VOC scavenging material used in solution and a preparation method thereof. Background technique [0002] VOC is seriously harmful to the environment. Catalytic decomposition and degradation of VOC is one of the key means to solve environmental and energy problems. Among many photocatalytic materials, TiO is mostly supported by porous solid materials. 2 However, the cost of solid materials is high and the replacement is difficult, while ordinary TiO 2 The light-restricting factor is large, especially the catalytic utilization rate of visible light is extremely low, which seriously limits the catalytic effect. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a VOC scavenging material for use in solution and a preparation method thereof, which can obtain an aqueous solution VOC s...
