以纳米ZnO为载体,采用金属离子掺杂的方法制备了Ag/ZnO复合抗菌剂。通过TEM、XRD和XPS等技术对样品进行表征。实验结果表明:制备的Ag/ZnO复合粉体是一种纳米复合抗菌剂,粒径在18nm左右,并且银以Ag2O的化学态存在于Ag/ZnO复合粉体表面,在ZnO的位置上进行了有效掺杂。掺杂银有效的提高了纳米ZnO的光催化性能以及抗菌效果。 Ag / ZnO composite antibacterial agent was prepared by metal ion doping using nano-ZnO as carrier. The samples were characterized by TEM, XRD and XPS techniques. The experimental results show that the prepared Ag / ZnO composite powder is a nano-composite antibacterial agent with a particle size of about 18 nm, and the chemical state of Ag2O exists on the surface of Ag / ZnO composite powder, and the position of ZnO Doping effectively. Doping Ag effectively improves the photocatalytic activity and antibacterial effect of nano-ZnO.
