Third Order Nonlinear Optical , Electrochemical, Catalytic and Antibacterial Properties of Green Synthesized BaSnO۳ Nanoparticles

Perovskite materials are widely studied for their super-conducting, magnetic, catalytic and electro-optic properties. Among them, barium stannate (BaSnO۳), finds applications in dielectric and optically active devices, thermally stable capacitors, humidity and gas sensors. In this study, BaSnO۳ was synthesized by chemical and greener methods and comparative analyses has been performed on their electrochemical, third order nonlinear, dye deactivation and bacterial suppression properties. Decreased crystallite size was realized for the green synthesized BaSnO۳. Energy band gaps were ۳.۲۳ and ۳.۰۴ eV for BaSnO۳ synthesized by normal and greener approach, respectively. The extract mediated sample exhibited increased specific capacitance value. Photocatalytic degradation efficiencies were ۷۸.۴% and ۸۹.۷%, respectively for BaSnO۳ synthesized by normal and greener approach against methyl violet after ۹۰ min of UV light irradiation. Enhanced nonlinear optical parameters were obtained for the extract mediated BaSnO۳. Excellent antibacterial efficacy against Proteus vulgaris bacteria was realized for the greener BaSnO۳ NPs thanks to the domination of phytochemicals of M. olifera leaf extract.
