Abstract

The invention discloses a rubidium and tungsten co-doped titanium dioxide photocatalytic material and a preparation method thereof. According to the photocatalytic material, titanium dioxide is doped with rubidium and tungsten elements, and the molar doping ratio of the rubidium and tungsten elements is 0.01%-5.0%. The photocatalytic material is grey white powder. The preparation method comprises the following steps: (1) uniformly mixing absolute ethyl alcohol, acetic acid and deionized water, adding rubidium nitrate and sodium tungstate into the mixture, fully dissolving, and regulating the pH value of the solution to 0.5-7.0 by using nitric acid to obtain a solution A; (2) dissolving butyl titanate in absolute ethyl alcohol of which the volume is equal to that of the absolute ethyl alcohol in the step (1) to obtain a solution B; (3) slowly dropwise adding the solution B into the rapidly stirred solution A, continuously stirring after dropwise adding until gel is formed, and aging and air-drying the gel; and (4) grinding the obtained xerogel into powder, and roasting the powder in a muffle furnace to obtain the rubidium and tungsten co-doped titanium dioxide photocatalytic material.
