titleOfInvention | Preparation and application of nano-micron silicon particle composite titanium dioxide photocatalyst |
abstract | The invention discloses a preparation method of a titanium dioxide photocatalyst compounded by nano-micron silicon particles, which is characterized in that titanium dioxide particles are compounded on the surface of silicon particles after silicon chips or silicon waste liquid produced by photovoltaic production is extracted and cleaned to prepare the titanium dioxide photocatalyst doped with silicon powder. Compared with the prior art, the composite photocatalyst has the advantages of uniform granularity, large specific surface area and good visible light band absorption characteristic, fully utilizes silicon powder waste particles in the photovoltaic industry as dopants, realizes the preparation of the composite photocatalyst which changes waste into valuable, has good environmental friendliness, and has a surrounding structure of titanium dioxide nano particles compounded by nano-micron silicon particles, wherein the core is silicon particles, can absorb near infrared light, enhances the generation of photo-generated electron-hole pairs, and has simple process, easily available raw materials and low cost, thereby being beneficial to industrial scale production prospect. |
