| titleOfInvention | Visible light catalytic nano antibacterial material and preparation method thereof |
| abstract | The invention belongs to the field of nano antibacterial materials and environmental protection, and particularly relates to a visible light catalytic nano antibacterial material and a preparation method thereof. The antibacterial material is GaN-ZnO quaternary alloy nano particles which take GaN as a main crystal lattice and ZnO is in solid solution. Wherein the solid solubility of ZnO is 23-30 at%, and the forbidden band width is 2.3-2.6 eV. The nano antibacterial material has a large specific surface area and a proper energy band structure, and has excellent visible light absorption performance while ensuring strong redox capability. Zn 2+ And Ga 3+ The release of ions and OH generated under illumination cause the destruction of bacterial cell walls, thereby effectively killing bacteria. The invention obtains the single-phase quaternary alloy material with high crystallization quality by controlling the nucleation temperature, the airflow field and the reactant, solves the problems of narrow photoresponse waveband, low antibacterial efficiency and poor antibacterial universality of the existing photocatalytic antibacterial material,and poor effect of photocatalytic degradation of organic matters. |
