Antibacterial and photo catalytic activity of pomegranate rind extract doped tio2 nanoparticles by sol-gel method

Metal oxides  exhibits extraordinary properties  like hydrophobic nature and high energy band gap, hence it can be used in different types of applications such as in solar cell, photo catalysis, charge spreading devices, chemical sensors, microelectronics, electrochemistry, antibacterial products and textiles in the nano level due to their high surface to volume ratio. Generally various synthesis techniques are available to prepare TiO2nanoparticles. In this present paper synthesis of TiO2nanoparticles were focused using Green synthesis using pomegranate rind extract as one of precursor. Pure TiO2 exhibits low photocatalytic property due to rapid recombination of photo-activated electrons and holes. Extract of Pomegranate Rind (PRE)   was considered to dope into TiO2photocatalyst in order to enhance the photocatalytic property and bacterial inactivation efficiency. The PRE doped TiO2 nanoparticles were prepared by sol-gel method and calcined at 400°C for 2h. The synthesized powders were characterized by Uv-Vis, XRD, SEM, FT-IR. Photocatalytic activity and bacteria killing effect was determined by means of degradation of methyl orange solution and inactivation of E.Coli bacteria. PRE doped TiO2 has an effect on inhibition of anatase crystal growth, led to the enlargement of the composite specific surface area exhibits highest photocatalytic activity and E.Coli inactivation efficiency.
