摘要

The impacts of addition of organic compound (anionic surfactant) dodecylbenzenesulphonate (DBS)on the electrodeposition of nickel oxide (NiO x ) nanoparticles and on the electrocatalytic oxidation ofglucose from alkaline solution are studied. NiO x nanoparticles are electrodeposited on the surface of aglassy carbon (GC) electrode in the presence and absence of the DBS. Cyclic voltammetry (CV), fieldemission-scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) areused for characterization of the above electrodes. The peak current of the redox couple Ni(II)/Ni(III)increases with the [DBS] before it decreases at [DBS] > 1×10 -4 M. The electrocatalytic activity of theNiO x /GC electrode towards the electrochemical oxidation of glucose is affected by the same manner.An attempt to correlate this electrocatalytic enhancement with the addition of the DBS is introduced.Optimum concentration of the DBS is obtained that gives the best enhancement in the electrochemicaland electrocatalytic properties.
