Catalytic Response of Transition metals (Ni, Co & Cu) Doped SiO2: TiO2 Nanocomposite Under Natural Sun Light

Catalysis is the acceleration of a photo reaction in the presence of a catalyst. Dye degradation is a process in which the large dye molecules are broken down chemically into smaller molecules. Dye degradation with photo catalysis takes place through photo sensitization and photo oxidation. It depends on the electronic structure, especially band structure of the catalyst and the dye.  According to:  Degradation efficiency (%) = [1- (Ct/C0)] X 100  Where,  Ct is the concentration after time t  C0 is the initial concentration
