Preparation method and application of zinc oxide/silver oxide composite photocatalyst |
| abstract |
The invention discloses a preparation method and application of a zinc oxide/silver oxide composite photocatalyst, wherein a zinc-based precursor is prepared by adopting a liquid-phase coprecipitation method, porous spongy zinc oxide is prepared by high-temperature calcination, silver nitrate is used as a precursor, sodium hydroxide is added to react under the alkaline environment condition of pH =13, silver oxide nanoparticles are obtained by drying, and the obtained porous spongy zinc oxide and silver oxide nanoparticles are subjected to physical mixing processes such as magnetic stirring under the alkaline condition to obtain the composite photocatalyst with silver oxide nanoparticles loaded on the surface of zinc oxide. ZnO/Ag prepared by the invention 2 The O composite material has the advantages of large specific surface area, high active sites of photocatalytic reaction and the like, and can be used for photocatalytic degradation of formaldehyde liquid under visible light. |
