Bindu, K.Sridharan, K.Ajith, K.M.Lim, H.N.Nagaraja, H.S.2026-02-052016Electrochimica Acta, 2016, 217, , pp. 139-149134686https://doi.org/10.1016/j.electacta.2016.09.083https://idr.nitk.ac.in/handle/123456789/25883Electrochemical sensors and supercapacitors are two noteworthy applications of electrochemistry. Herein, we report the synthesis of SnFe<inf>2</inf>O<inf>4</inf> microcubes and Fe<inf>2</inf>O<inf>3</inf> nanorods through a facile microwave assisted technique which are employed in fabricating the electrodes for nonenzymatic hydrogen peroxide (H<inf>2</inf>O<inf>2</inf>) sensor and supercapacitor applications. SnFe<inf>2</inf>O<inf>4</inf> microcubes exhibited an enhanced specific capacitance of 172 Fg?1 at a scan rate of 5 mVs?1 in comparison to Fe<inf>2</inf>O<inf>3</inf> nanorods (70 Fg?1). Furthermore, the H<inf>2</inf>O<inf>2</inf> sensing performance of the fabricated SnFe<inf>2</inf>O<inf>4</inf> electrodes through chronopotentiometry studies in 0.1 M PBS solution (at pH 7) with a wide linear range revealed a good sensitivity of 2.7 mV ?M?1 ?g?1 with a lowest detection limit of 41 nM at a signal-to-noise ratio of 3. These results indicate that SnFe<inf>2</inf>O<inf>4</inf> microcubes are excellent materials for the cost effective design and development of efficient supercapacitors as well as nonenzymatic sensors. © 2016 Elsevier LtdCost effectivenessElectrochemical sensorsElectrochemistryElectrodesFerriteHydrogen peroxideNanorodsOxidationPeroxidesSignal to noise ratioCost effective designElectrochemical performanceHydrogen peroxide sensorMicrowave-assisted methodsMicrowave-assisted techniqueNon-enzymatic sensorsSuper capacitorSupercapacitor applicationMicrowave sensors
