Title: Sonochemical synthesis of manganese (II) hydroxide for supercapacitor applications

Graphical abstract: - Highlights: • Octahedral Mn(OH){sub 2} nanoparticles were prepared by sonochemical process. • TEM images indicates the formation of octahedral Mn(OH){sub 2} nanoparticles. • Octahedral Mn(OH){sub 2} nanoparticles are evaluated as a supercapacitor material. - Abstract: In this research, a rapid and controllable synthesis of octahedral Mn(OH){sub 2} nanoparticles with a size range from 140 to 200 nm has been done by a sonochemial irradiation method for the energy storage applications. Transmission electron microscopic images, energy disperse X-ray spectroscopy (EDX), X-ray photo electron spectroscopy (XPS), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) analyses clearly indicate the formation of octahedral Mn(OH){sub 2} nanoparticles. Octahedral Mn(OH){sub 2} nanoparticles were evaluated as a supercapacitor material that exhibits specific capacitance 127 F g{sup −1} at a current density of 0.5 mA cm{sup −2} in the potential range from −0.1 to 0.8 V in 1 M Na{sub 2}SO{sub 4} solution.
