Preparation method of novel porous structure photocatalyst |
| abstract |
The invention belongs to the technical field of new materials, and particularly relates to a preparation method of a novel porous structure photocatalyst, which comprises the following steps: the method comprises the following steps: dissolving a titanium precursor in deionized water to prepare a 0.5M aqueous solution; step two: adding silica sol into the solution to serve as a precursor solution, atomizing the solution into micrometer-sized liquid drops through an ultrasonic atomizer, and taking silica microspheres with different sizes as hard templates; step three: then the liquid drops enter a high-temperature quartz tube type reactor under the assistance of carrier gas, and products are collected by adopting a glass fiber filter membrane; step four: calcining at 450 ℃ for 1 hour and etching with 10 wt% hydrofluoric acid at room temperature to obtain the titanium dioxide microsphere photocatalyst with a porous structure. The invention realizes the separation and reutilization of nano-sized titanium dioxide, has high catalytic efficiency, and can realize the comprehensive effect of industrial application by using the organic solvent and the template agent. |
