| titleOfInvention | Nitrogen-doped BiOIO3Preparation method and application of photocatalyst |
| abstract | The invention belongs to the technical field of nano material preparation and application, relates to a photocatalyst, and particularly relates to nitrogen-doped BiOIO 3 A method of preparing a photocatalyst, comprising: preparing equal-mole mixed solution of pentahydrate bismuth nitrate and potassium iodate, transferring the mixed solution into a hydrothermal reaction kettle for reaction for 4-16 h at the temperature of 120-160 ℃, naturally cooling, filtering, washing with water, drying and grinding to obtain BiOIO 3 Nanoparticles; adding BiOIO 3 Mixing and grinding the nanoparticles and urea, calcining the mixture for 2 to 6 hours at 180 to 260 ℃ in a muffle furnace, naturally cooling the calcined mixture, and grinding the cooled mixture to obtain the nitrogen-doped BiOIO 3 A photocatalyst. The invention also discloses application of the photocatalyst in photocatalytic degradation of organic pollutants in wastewater. The preparation method is simple and easy to implement, safe and environment-friendly, low in product cost, easy for industrial production, and high in application prospect and practical value. The prepared nitrogen-doped BiOIO 3 The photocatalyst effectively improves the visible light absorption performance of the material, improves the photocurrent intensity of the material, and strengthens the materialThe reaction activity of photon-generated electrons and holes has obvious effect of degrading organic pollutants by photocatalysis. |
