Electrochemical Fabrication and Characterization of a Gold-Polyaniline /Multi-walled Carbon Nanotubes/Manganese Dioxide Composite Electrode

Objectives: Electrochemical fabrication and characterization of a gold-polyaniline/multi-walled carbon nanotubes/manganese dioxide (Au-PANI/MWCNT/MnO2) composite electrode. Methods: The MnO2 nanoparticles (NPs) were prepared by heating 1% Mn(NO3)2.4H2O at 100 0C for 24 h and characterized by using Fourier transform infrared spectroscopy (FTIR) and Ultraviolet/visible (UV/Vis) spectrophotometry. The size and shape of the NPs were determined from the transmission electron microscopic image. MWCNTs were functionalized with carboxyl groups on their sidewalls by sonicating in H2SO4:HNO(3:1, v/v) for 12 h at 40 kHz. The functionalization was further confirmed through UV/Vis spectrophotometry. The working Au surface was first activated and then electropolymerized by using 50 μl of 0.005% C6H5NH2 in 01 N HCl followed by electrodeposition with 0.1% each of the c-MWCNTs and manganese oxide NPs through 20 cycles of cyclic voltammetry (-0.2-0.9 mV) at the rate of 20 mV/s. The Au-PANI/MWCNT/MnO2 composite was then characterized by using FTIR spectra and scanning electron microscopy. Findings: An Au-PANI/MWCNT/MnO2 composite electrode was fabricated and characterized. Novelty: The nanocomposite electrode was designed by using screen printed electrode, which is very simple to construct, portable, and economic. The composite can be used to design a sensors or sensor array in future.
