“…It is known that nickel oxide is an electrocatalyst for hydroxylated organic compounds 10 [5,6,27,28]. It is envisaged that this composite material may retain and enhance the catalytic properties of the nickel oxide through fine dispersion of the catalyst particles into the conductive PAni matrix to result in a drastic increase in surface area.…”

The morphologies and elemental components of the films were inspected by Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Diffraction (EDX). The stability of nickel oxide in the films was found to be enhanced against acidic environments. Electrochemical catalytic behavior of NiO x within the composite film was conserved and demonstrated by catalytic oxidation of methanol and ethanol.

“…Electrochemical catalysis is very suitable for lowering the potential required to oxidize various organic substances [16]. The electrocatalytic detection of several classes of organic compounds by incorporating nickel and cobalt species into the glassy carbon surface was achieved at reasonable potential values [16][17][18].…”

The electrocatalysed oxidation of histamine on a thin film nickel electrode was investigated for the purpose of its chronopotentiometric determination. The oxidation mechanism implies complex and combined processes of histamine physical adsorption and consequent oxidation via joined oxidation potency of a constant current and electrochemically generated nickel-oxihydroxide, which played a role of an electron transfer catalyst. Experimental parameters affecting the oxidation process, including type and concentration of supporting electrolyte, initial potential, oxidation current, temperature and concentration time, were optimised. Using a 240 s accumulation time, limit of detection and quantitation were 0.11 mg L À1 and 0.29 mg L À1 of histamine, respectively.

An amperometric alcohol sensor by using electroless nickel as working electrode was developed. The sensing results were affected by the electrolyte composition, deposition time, and temperature of the electroless nickel. The results revealed that the best operating conditions of the electroless nickel were 70 C deposition temperature, 20 min deposition time, and 2.632 ratio of reducing agent to nickel ion in the solution. The results also indicated that the response time of the prepared alcohol sensor is in the range from 10 to 13 s and the best sensitivity is 8.7 mAappm6cm 2 .
