“…When the 5 mM glucose is added in the NaOH electrolyte, a visible shoulder wave centered at 0.6 V is responsible for the electrooxidation of glucose where Cu (III) and hydroxyl radicals are probably involved [27,28]. Moreover, in the cathodic scan, the disappearance of peak IV provides evidence that the Cu (III) is consumed in the electrooxidation of glucose.…”

In this study, copper/nickel (CuNi) particle decorated multiwalled carbon nanotubes (MWCNTs) have been fabricated for nonenzymatic glucose detection by the electrodeposition of CuNi particles on a glassy carbon electrode (GCE) modified with Nafion-functionalized MWCNTs (fMWCNTs). Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses reveal that CuNi particles were successfully deposited on the fMWCNTs/GCE. The as-synthesized CuNi/fMWCNT composite reveals the shape characteristics of dendrite with a Cu/Ni atomic ratio of around 88.1/11.9. The nonenzymatic glucose sensor based on CuNi/fMWCNT composite shows excellent electrocatalytic activity toward glucose oxidation with a high sensitivity (1470.2 μA cm −2 mM −1 ), a low detection limit (2.5 nM, signal/noise (S/N) ratio=3), and a wide linear range (0.1-5000 μM). Moreover, the sensor has been successfully used for the assay of glucose in human serum samples with good recovery, ranging from 95.6 to 100.1 %. These results indicate that CuNi/fMWCNT composite is an ideal candidate for novel nonenzymatic glucose sensor because of its high sensitivity, good selectivity, good stability, and low cost.

“…The activity of our electrodes (either GC OX-AL or GC OX-AC ) expressed in mA cm -2 were compared with those in literatures at similar conditions. It was found that it is higher than Ni(OH) 2 -Zeolite/CPE [53], Ni(OH) 2 -chitosan/GC [54], GO-NiO/GC [55], NiO x /GC [6], Cu-ZnO/GC [56] and it was found to be closer to CuO x /Cu [57], NiO x -MWCNT/GC [58] and Cu-NPS/GC [59]. In the other the activity of the electrode in this work was found to be lower in performance than Ni-NPS/ GC [60] and NiO x (sol-gel)/GC [26].…”

Usually, glassy carbon electrode (GC) is used as it is as a substrate for electrochemically deposited nickel or nickel oxide (NiO x ) nanoparticles. In the present study, GC carbon is anodically oxidized in different media prior to electrode position of NiO x and the impacts of this pretreatment on the structural and electrochemical characteristics of NiO x are studied. Upon anodic pretreatment of GC electrode in acid (0.1 M H 2 SO 4 , GC OX-AC ) and in alkali (0.1 M NaOH, GC OX-AL ), the structural and electrochemical characterizations of nickel oxide (NiO x ) nanoparticles are highly modified. Cyclic voltammetry (CV), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) are used for characterization of the electrodes. While NiOx nanoparticles deposited on GC OX-AC reveal a bird-like shape, it shows semi-spherical shape when it is deposited on either GC or GC OX-AL , with smaller size on the GC OX-AL . The reversibility of the Ni(OH) 2
