Microwave Synthesis, Characterization and Photocatalytic Properties of SnO2 Nanoparticles

Abstract

In the present endeavour, SnO 2 nanoparticles (NPs) were synthesized using microwave method. Synthesized SnO 2 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. SnO 2 NPs were of spherical mor-phology having crystallite size of 35.42 nm as obtained from Scherrer's formula using most intense peak of XRD. Syn-thesized NPs were used for photodegradation of melthylene blue (MB) dye under UV light. The SnO 2 NPs ware found to have photodegradation efficiency and apparent rate constant of 55.97% and 2.149 × 10 −2 respectively.
