Abstract :
SnS nano-flakes are synthesized by solvothermal process and characterized well by X-ray diffraction (XRD) and scanning electron microscope (SEM). Widths of the as-synthesized SnS nano-flakes vary from 100 nm to several micrometers whereas thicknesses of these SnS nano-flakes vary from 70-80 nm. Chemical purity and stoichiometric ratio of the SnS nano-flakes are observed by energy dispersive analysis of X-rays (EDAX). Thermal stability of the SnS nano-flakes is investigated by thermo gravimetric analysis (TGA). Different kinetic parameters such as activation energy (E), Arrhenius parameter (A) and entropy change (DeltaS) are calculated by Redfern-Coats and Satava model.
