Experiment on Nano-Sized Activated Carbon/Zn-MnO2 Electrode Material

Abstract:

Here Zn-doped MnO2 nano-material was synthesized by sol-gel method and comprised the composite electrode material with activated carbon nano-particles with different pore size distributions by roller vibration milling at room temperature. The microstructure and electrochemical performance of the nano-composite electrode materials were studied by AFM, XRD and electrochemical methods. The activated carbon nanomaterial displays spherical particles with 50nm mean size. Meanwhile the AC nano-particles combined with 10wt.% Zn- MnO2 material possess improved electrochemical property with specific capacitance up to 299 F/g.
