| description | The invention relates to an easy-to-recycle reusable nanocrystalline TiO2 coated hollow glass microsphere photocatalyst. A preparation method comprises the following steps: firstly dispersing hollow glass microspheres into deionized water, and stirring and dispersing; then, heating the solution to a certain temperature, using the TiCl4 solution as a precursor and slowly dropwise adding the precursor into the hollow glass microsphere solution, carrying out in-situ synthesis of the photocatalyst nanocrystalline TiO2 on the surface of the hollow glass microsphere; then aging the mixture for a certain time; finally, filtering and washing the product with water, and drying to obtain the easy-to-recycle reusable nanocrystalline TiO2 coated hollow glass microsphere photocatalyst. The photocatalytic sewage treatment agent disclosed by the invention has the performance of efficiently degrading organic pollutants in wastewater with light, and the density is less than the density of water, so that the recycling of the p |
