| titleOfInvention | Preparation method and application of nitrogen-doped nano-silica photocatalyst |
| abstract | The invention discloses a preparation method and application of a nitrogen-doped nano-silica photocatalyst, and belongs to the technical field of photocatalysis. The preparation method comprises the following steps: mixing a nitrogen source and a sodium silicate solution, adding acid to form a precipitate, and aging, washing, drying, roasting and grinding the precipitate to obtain the nitrogen-doped nano-silica photocatalyst. The catalyst has a spherical shape, the particle size is 100-200 nm, and the doping amount of nitrogen atoms accounts for about 5-6% of the total atomic number. The invention also includes the application of the catalyst in the aspect of photocatalytic degradation of organic pollutants on the surface of a solid phase, and is characterized in that a reaction medium can be a water phase or a gas phase, and simulated natural light irradiation is adopted as a light source. The method adopts a precipitation method to synthesize the nitrogen-doped nano-silica photocatalyst, has the advantages of simplicity, good repeatability and high yield, adopts the simulated sunlight to drive the reaction, and has good catalytic effect on various types of organic pollutants. |
