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.
