Popis: | High performance MnSn(OH)6 electrodes employing solvothermal processing route for energy conversion was explored. Single phase tetragonal MnSn(OH)6 nanocubes were validated from sharp diffraction peak of crystal plane (2 0 0). Interaction with photons and nanocubes emissive character was deliberated. The characteristic Mn-O, Sn-O and OH vibrations of MnSn(OH)6 nanocubes were evaluated. Uniform nanocube formation and its dispersive nature were examined. Fabrication of scalable high performance MnSn(OH)6 electrodes was achieved by standard coating method and systematically analyzed to evaluate its electrocatalytic performance for energy applications. 525F/g specific capacitance at 5 mV/s achieved in favor of uniform nanocube morphology of MnSn(OH)6 electrode. Obtained product yielded an outstanding linear sweep voltammetry (LSV) result of 281 mA/g for 10 mV/s whose electrical conductivity, electron mobility and charge transfer kinetics were investigated by electrochemical impedance spectra (EIS) and the superior stability over 5 h of electrochemical oxygen evolution reaction (OER) activity also proposed. High performance MnSn(OH)6 nanocube synthesis and fabrication was achieved for electrochemical energy conversion application. |
