Photocatalytic and electrochemical performance of hydrothermally synthesized cubic Cd2SnO4 nanoparticles

[Display omitted] •Cubic Cd2SnO4 nanoparticles was synthesized using a simple hydrothermal method.•Prepared cubic Cd2SnO4 nanoparticles possess specific surface area of 32.27m2/g.•Showed better photocatalytic property for methylene blue over methyl green dye.•Exhibited an impressive specific capacitance value of 112Fg−1. Herein, we report the synthesis of cubic Cd2SnO4 nanoparticles through a simple hydrothermal method. Effect of annealing temperature on phase transition of cubic Cd2SnO4 nanoparticles was observed from X-ray diffraction analysis and their structural parameters were determined. Results of thermo gravimetric/differential thermal analyses indicate two peaks, one at 674°C correspond to cubic phase and other one at 820°C which confirms the phase transition of the prepared nanoparticles from cubic to orthorhombic. FESEM and TEM images illustrate the cubic shaped morphology of the samples with their size around ∼25nm. From the optical measurements bandgap value of the prepared sample was estimated to be ∼2.59eV. Photocatalytic performance of prepared cubic Cd2SnO4 nanoparticles were studied by degrading methyl green and methylene blue dyes under UV-light irradiation for a time of 90min. Using cyclic voltammetry analysis electrochemical performance of the studied sample was investigated, which gave a capacitance value of 112Fg−1.
