Abstract
The present study is about an eco-friendly and cost effective method of using five potent plant extracts and sunlight as the reaction medium and grinding as a nano technique to prepare nano composite of tin (IV) oxide from tin metal. The equivalent preparation is widely used as a drug formulation in the treatment of spectrum of infectious diseases. The intensive grinding and calcinations with the plant material lead to the formation of nano crystallite with a tetragonal phase with an average crystallite size of 27nm. The elements Ca, P, Na, Mg and Fe at the microscopic level identified at the surface of the nano crystallite by the X – ray Photo Electron Spectroscopy showed the uniqueness of the synthesis. The formation of spherical crystallites with good distribution of pores was indicated by the electron microscopic images and adsorption studies. The presence of oxygen deficiency arising due to nonstoichiometry in the crystal lattice was evident from the Electron paramagnetic Resonance study. The free radical equivalent of DPPH radical calculated for the final stage sample was suggestive of its anti-oxidant property and hence it’s biological activity. The overall research study provided an alternative route of preparing nontoxic nano tin (IV) oxide composite with good biological activity apart from its already proven catalytic and sensor applications.
