- Abstract
Chemically produced coppercontaining MnO2 nanoparticles were studied using FTIR, UV-Vis spectroscopy, XRD, AFM, cyclic voltammetric and charge/discharge behaviour. Mixed nanocomposites have a crystalline size of 50 nm was calculated through Debye Scherrer's equation from XRD analysis. The FTIR spectra were recorded region 400-4000 cm-1, of clean and doped Manganese dioxide nanoparticles. Mn-O can be ascribed to the stretching vibration band of MnO2 nanoparticles at 631 cm-1. The bending and stretching vibrations of the O-H group are ascribed to the fundamental absorption peaks at 1620 cm-1 and 3400 cm-1.AFM is used to characterize the impact of surface roughness on the fundamental properties of MnO2, copper induced nanocomposites of MnO2 particles. Electrochemical impedance and voltammetric experiments are used to investigate the behaviour of individual and mixed nanocomposites as supercapacitors.
