Description |
In this work, electrodeposition of Co-Ni alloy nanostructures was performed on copper foam and directly applied as an electrocatalyst for the electrooxidation of acetaminophen (Paracetamol) and its detection. The surface morphology and the elemental composition were investigated using SEM and EDX analyses respectively. The
observed morphology was similar to nano cones that are uniformly grown on the electrode surface. EDX analysis
also confirmed the presence of both cobalt and nickel in the electrodeposit. The preferred orientation lies in
(002) and (110) planes of cobalt and nickel respectively that confirmed the formation of alloy. Electrooxidation
of acetaminophen was carried out using cyclic voltammetric method in 0.1M NaOH solution. On addition of
acetaminophen, an apparent anodic oxidation current enhancement was observed with lesser overpotential than
cobalt and nickel electrodes which revealed the excellent electrocatalytic activity of the material. Interference
studies also revealed the good selectivity for acetaminophen even in the presence of some interfering species.
The reproducibility and stability was checked for the proposed Co-Ni alloy modified electrode. The analytical
applicability was examined using the commercial paracetamol tablets and the recovery results were also good.
The above results revealed that Co-Ni modified electrode on copper foam is a suitable candidate for electrochemical detection of acetaminophen.
