Amorphous MnO2/carbon nanowalls composite films are developed for the supercapacitor applications. Synthesis of carbon nanowalls template is performed by plasma-enhanced chemical vapor deposition in a CO/H2 microwave discharge system. A well dispersion of amorphous MnO2 domains throughout carbon nanowalls template is obtained by potentiostatic anodic deposition technique. Carbon nanowalls enable to...
MnO2–chitosan hybrid nanocomposite films with low and high chitosan's molecular weights are synthesized by one-step cathodic electrodeposition on nickel foam substrate for electrochemical capacitors (ECs) application. The films have been characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), fourier transform infrared (FTIR) spectroscopy, cyclic voltammetry,...
Nanostructured MnO2 thin films were electrodeposited on carbon nanowalls (CNWs), which were grown first by microwave plasma enhanced chemical vapor deposition (MPECVD) on three-dimensional nickel foam substrates. The optimization theme for producing composite MnO2/CNW on large area electrodes for electrochemical supercapacitors is presented. The MnO2/CNW nanocomposite electrodes were characterized...
Nano-structured MnO2-chitosan hybrid composite electrodes containing low and high chitosan's Mw were synthesized by one-step cathodic electrodeposition on nickel foam substrate for electrochemical capacitors (ECs) application. The effect of chitosan molecular weight (Mw) on the structure and capacitive behaviour of the tailored electrodes was examined. The electrodes have been characterized using...
