A systematic investigation on the preparation of SnO₂ nanosheets using cost effective hydrothermal method was studied. Tetragonal phase SnO₂ were synthesized using tin(II)chloride dihydarte and sodium hydroxide as precursor solution with basic water mixing. The synthesized samples were examined by XRD, HRSEM, EDAX, FTIR and UV-visible spectroscopy. The nanocrystalline size and strain of the SnO₂ nanosheets have been inspected by Williamson-Hall analysis. The quantum size effect outcomes in spectacular variation in the optical and vibrational appearances of nanostructured materials likened to their bulk counterparts. Nanosheets like optical image were observed in the microscopy studies. Functional tests of SnO₂ nanosheets include photocatalytic effect in the degradation of methylene blue (MB). The result revealed that SnO₂ nanosheets degraded 84% of MB under UV light illumination. Dielectric studies such as dielectric constant, loss and ac conductivity were determined.
