Preparation of supporting photocatalysts for water treatment using natural sunlight as an alternative driving energy

The present study focus on synthesis of visible-light active pure, Fluoride (F) - and Silica (Si)-doped titanium dioxide (TiO2) photocatalyst. Designing the nanoparticles under sol–gel process method is adopted. Characterizations such as SEM, XRD, FTIR, DLS revealed about crystallinity, physico-catalytic properties photocatalysts. nanomaterials were tested for their photocatalytic against crystal violet, methyl orange, oil grease chemical oxygen demand (COD) remediation. To check degradation efficiency samples kept in different light sources namely natural sunlight, dark + sunlight LED using UV–Vis spectroscopy. It noteworthy that as-synthesized materials best acted target parameters (visible range) which a renewable energy taken an alternative driving energy. Specifically, Si-doped TiO2 was found to be superior over F-doped pure (undoped) terms efficiencies.
