Nano-manganese oxide loaded on titanium electrocatalytic membrane electrodes (nano-MnOx/Ti) were synthesized bysol-gel method using porous Ti membrane as a substrate and the manganese acetate as a raw material without releasing NOx. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Field-emission scanning electron microscopy (FESEM) were employed to characterize crystal form, valence state and surface morphology of nano-MnOx, respectively. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and chronoamperometry (CA) were used to investigate the electrochemical properties of nano-MnOx electrode. The results indicated that the MnOx catalysts consisted of γ-MnO2 and Mn2 …

The polyaniline-carbon (PAnC) electrode was prepared by the polymerization of aniline monomer and activated carbon in ice water bath, and followed by chemical deposition of manganese dioxide MnO2-PAnC composite material. The specific capacitance of MnO2-PAnC reached 459 F•g-1. The cyclic voltammetric results showed a small deformation in the voltammogram curve obtained with the MnO2-PAnC electrode at high scan rate, indicating good reversibility and capacitive properties. The AC impedance results revealed that the MnO2-PAnC electrode displayed the smallest charge transfer resistance and the fastest diffusion
