| titleOfInvention | A kind of zinc-copper-aluminum-erbium composite oxide and its preparation method and application |
| abstract | The invention relates to a zinc-copper-aluminum-erbium composite oxide and a preparation method and application thereof, belonging to the field of photocatalytic materials. The zinc-copper-aluminum-erbium composite oxide of the present invention has a chemical structural formula: Zn 14.4 Cu 3.6 Al 6‑x Er x O 27 , where x=2‑0.2; it is in an irregular layered structure, and part of it has a layer similar to hydrotalcite shape structure, particle size 10‑150nm. The zinc-copper-aluminum-erbium composite oxide of the present invention, through the doping of erbium ions, generates defect energy levels, captures photogenerated carriers, and promotes the separation of photogenerated carriers excited by near-infrared light. Organic pollutants produce good photocatalytic degradation, and under the irradiation of ultraviolet light and visible light, they all produce good catalytic degradation to organic pollutants; The adsorption removal rate of base orange was significantly improved. The present invention also provides a preparation method of Zn 14.4 Cu 3.6 Al 6-x Er x O 27 and its application as a photocatalytic degradation reaction catalyst under the irradiation conditions of near-infrared light, ultraviolet light and visible light. |
