Nanoparticles have a high surface area, exhibit better physical and chemical properties, and are commonly used in plastic rubber additives to improve or enhance the properties of the application. There are many methods of making nanoparticles that are commercially available. The laser ablation method uses pulsed energy to generate nanoparticles from the surface of the object. This is an important method for making various nanoparticles, especially nano-particles with complex phases or phases. With the use of the microstructure and the crystal phase of the target material, the polycrystalline phase nanoparticles can be obtained through the adjustment of the separation conditions, and the particles have a circular appearance below 50 nm, the composition of the nanoparticles is composed of a target material, the reactivity Gas and laser energy decisions. Using the reduction effect of titanium oxide photocatalyst, silver particles are further coated on the surface of the nanoparticles, and the nanoparticles with the core-shell structure have more characteristics and have greater potential for application.
