Green synthesis of titanium dioxide nanoparticles and their multifaceted applications

Herein, we have prepared TiO2 photocatalyst using simple solution evaporation method for degradation of dye contaminant. The structural and optical possessions of the prepared photocatalyst have been categorized by a series of methods such as FTIR, XRD, SEM coupled with EDAX and UV-DRS. The photocatalytic activity of the obtained TiO2 nanoparticles were investigated by monitoring the degradation of solution of Methylene Blue (MB) as model dye molecule, using simulated solar irradiation. Photo-degradation experimental results point out that the prepared TiO2 photocatalyst exhibits advanced photocatalytic action over commercially available powder TiO2. The bacterial activity of TiO2 nanoparticles monitored by using E.coli and S.aureus bacterial strains. The antimicrobial activity of the synthesized sample shows a good result against gram positive bacteria. The synthesized nano materials have great prospective to contribute in the wastewater treatment and bio-medical management technologies.
