A novel enzymeless glucose sensor based on nickel oxide (NiO) nanoparticles electrodeposited on reduced graphene oxide–copper oxide nanocomposite bulk modified carbon ceramic electrode (rGO–CuO/CCE) was reported. The prepared NiO/rGO–CuO/CCE was characterised by scanning electron microscopy, energy-dispersive X-ray spectroscopy, atomic-force microscopy, electrochemical impedance spectroscopy (EIS)...
In this work, vacancies diffusion length scale or the size of the nanostructures involved during oxidation when utilizing the Kirkendall phenomenon is presented. Ni nanowires with different diameters are formed by electrodeposition of Ni into anodic aluminium oxide (AAO) membrane. The oxidation of the dispersed Ni nanowires is carried out either via rapid thermal oxidation (RTO) or conventional furnace...
Different metal (Bi, Ni, La, Ce and Er) doped PbO2 electrodes were successfully prepared by electro-deposition method, and their electrocatalytic degradation capacity for 2, 4-dichlorphenol (2, 4-DCP) in water was compared in a batch experiment. The electrodes were characterized by scanning electron microscope (SEM). The morphology and component analysis showed that metal (Bi, Ni, La, Ce and Er) was...
TiO2-containing ceramic coatings were deposited on the surface of aluminium alloys by micro-arc oxidition. Surface and cross-section topograph of ceramic coating were observed using scanning electron microscopy (SEM). The phase composition of ceramic coating was analyzed by X-ray diffraction (XRD). The results showed that ceramic coating surface became smoother, whereas micro pores decreased and outer...
Gold nanoparticles (NPs) of 10-50 nm in diameter were synthesized on nitrogen incorporated diamond-like carbon (DLC:N) thin film electrode by electrodeposition. The deposition process of Au was investigated by cyclic voltammetry and chronoamperometry. The morphology of Au NPs was characterized by scanned electron microscopy. The potentiostatic current-time transients showed a progressive nucleation...
