Abstract

In the present endeavour, SnO₂ nanoparticles (NPs) were synthesized using microwave method. Synthesized SnO₂ NPs were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectrscopy (EDS) to find their structure, morphology and elemental composition. SnO₂ NPs were of spherical morphology having crystallite size of 35.42 nm as obtained from Scherrer’s formula using most intense peak of XRD. Synthesized NPs were used for photodegradation of melthylene blue (MB) dye under UV light. The SnO₂ NPs ware found to have photodegradation efficiency and apparent rate constant of 55.97% and 2.149 × 10^_2 respectively.
