Nickel oxide (NiOx) and polyaniline (PAni) were
electrocodeposited from NiSO4 and aniline through cyclic
voltammetric scans to afford PAni–NiOx composite film at
controlled pH environment. The electrochemical activities of
the film were investigated by cyclic voltammetry in 0.1 M
NaOH and 0.1 M H2SO4, respectively. Typical redox couples
of PAni in 0.1 M H2SO4 appeared at approximately 0.2 and
0.4 V vs. saturated calomel electrode (SCE); Ni(II)/Ni(III)
redox couple was observed at approximately 0.4 V vs. SCE in
0.1 M NaOH. The morphologies and elemental components
of the films were inspected by scanning electron microscopy
and energy dispersive X-ray diffraction. The stability of nickel
oxide in the films was found to be enhanced against acidic
environments. Electrochemical catalytic behavior of NiOx
within the composite film was conserved and demonstrated
by catalytic oxidation of methanol and ethanol.
