Abstract

The invention relates to an efficient NO degradation glass fiber cloth in-situ loaded BiOCl photocatalytic material. The efficient NO degradation glass fiber cloth in-situ loaded BiOCl photocatalyticmaterial comprises glass fiber cloth and BiOCl layers. The BiOCl layers grow on the glass fiber cloth in an in-situ manner, and BiOCl nano-sheets are densely assembled to obtain the BiOCl layers. A method for preparing the efficient NO degradation glass fiber cloth in-situ loaded BiOCl photocatalytic material includes 1), soaking the glass fiber cloth in hydrofluoric acid solution and then washingand drying the glass fiber cloth for standby application; 2), soaking the glass fiber cloth in saturated solution of bismuth nitrate pentahydrate, then taking the glass fiber cloth out of the saturated solution and draining solution attached to the surfaces of the glass fiber cloth; 3), soaking the glass fiber cloth obtained at the step 2) in potassium chloride solution, then taking the glass fiber cloth out of the potassium chloride solution and draining solution attached to the surfaces of the glass fiber cloth; 4), repeatedly carrying out the step 2) and the step 3) and ultimately drying the glass fiber cloth to obtain the BiOCl photocatalytic material on the basis of the glass fiber cloth.

Description

technical field [0001] The invention belongs to the technical field of inorganic materials, and in particular relates to a BiOCl photocatalytic material based on glass fiber cloth and a preparation method thereof. Background technique [0002] Bismuth oxychloride is an inorganic material, mostly used in the pigment market. Recently, bismuth oxychloride as a new type of photocatalyst has attracted widespread attention. Previous studies have shown that bismuth oxychloride has better photocatalytic activity than commercial titanium dioxide P25 and other catalysts under full light irradiation. Chinese patent CN101879455B provides a photocatalyst, bismuth oxychloride, which is used for photocatalytic oxidation of organic matter in water. The research results show that the bismuth oxychloride photocatalyst has good photocatalytic activity, and can be used in sunlight and simulated sunlight. The effect is comparable to that of the commercialized P25 photocatalyst; under the irrad...
