| titleOfInvention | Preparation of nano-silver/silicon particle composite titanium dioxide photocatalyst |
| abstract | The invention discloses a preparation method of a titanium dioxide photocatalyst compounded by nano silver/silicon particles, which is characterized in that nano silver particles are compounded on the surfaces of silicon particles extracted from silicon chips or silicon waste liquid, and then titanium dioxide particles are compounded on the surfaces of the silver/silicon particles to prepare the titanium dioxide photocatalyst compounded by the silver/silicon particles. Compared with the prior art, the photocatalyst has the characteristics of uniform granularity, large specific surface area and good visible light wave band absorption, wherein the core is silicon particles, the near infrared light can be absorbed, the generation of photoproduction electron-hole pairs is enhanced, the electron hole transfer and the surface plasma resonance effect are enhanced through the increase of the composite structure and the silver particles, the absorption effect of titanium dioxide serving as the photocatalyst in the visible light wave band is greatly improved, the process is simple, the raw materials are easy to obtain, the cost is low, and the photocatalyst is beneficial to industrial mass production. |
