Synthesis and Characterization of TiO2 1% SiO2 of Crystal and its Bacterial Applications
Abstract: Three-dimensional (3D) TiO2 Anatase and Rutile structures have attracted much attention due to their optical properties. However, the large band gap of (3.2 eV) results in the fact that anatase TiO2 can act as photo catalyst and be excited by UV light, which only accounts for 3–5% of the solar energy. On considering that nobel metallatic nanomaterials can harvest visible light, in this paper, TiO2 and SiO2 nanocrystals with rod …
