Application of copper oxide nanoparticles modified glassy carbon electrode for electrocatalytic oxidation of methanol
Copper nanoparticles were fabricated by electro-reduction of CuSO4solution in the presence of cetyltrimethylammonium bromide (CTAB) cationic surfactant as an additive through potentiostatic method. The prepared copper nanoparticles were characterized by scanning electron microscopy (SEM) and electrochemical methods. The SEM images reveal that the nanoparticles with diameters at about 70 n...
متن کاملSurface Modification of Glassy Carbon Electrode by Ni-Cu Nanoparticles as a Competitive Electrode for Ethanol Electro-Oxidation
In the present study, Nickel-Copper nanoparticles were electrodeposited on glassy carbon electrode (GCE) by using electroplating deposition method. The prepared electrode was characterized by scanning electron microscopy (SEM) and elemental mapping analysis. Results showed that Ni-Cu nanoparticles with a high density are distributed at the surface of the glassy carbon electrode. Subsequentl...
متن کاملGold Nanoparticles/Carbon Nanotubes Composite Film Modified Glassy Carbon Electrode Determination of Meclofenoxate Hydrochloride
A novel voltammetric sensor based on gold nanoparticles (GNPs) and single-walled carbon nanotubes (SWNTs) composite was developed. The nanocomposite modified electrode was characterized using atoms force microscope (AFM). The electrochemical behavior of meclofenoxate hydrochloride (MFX) was investigated on this sensor. The results indicated that the GNPs/SWNTs modified electrode exhibited effic...
متن کاملThe Enhanced Photo-Electrochemical Detection of Uric Acid on Au Nanoparticles Modified Glassy Carbon Electrode
In this work, a sensitive and novel method for determining uric acid (UA) has been developed, in which the glassy carbon electrode (GCE) was modified with electrodeposition Au nanoparticles and used to monitor the concentration of UA with the assistant of visible light illumination. The morphology of the Au nanoparticles deposited on GCE surface were characterized by scanning electron microscop...
متن کاملDirect Electrochemistry of Hemoglobin Immobilized on a Functionalized Multi-Walled Carbon Nanotubes and Gold Nanoparticles Nanocomplex-Modified Glassy Carbon Electrode
Direct electron transfer of hemoglobin (Hb) was realized by immobilizing Hb on a carboxyl functionalized multi-walled carbon nanotubes (FMWCNTs) and gold nanoparticles (AuNPs) nanocomplex-modified glassy carbon electrode. The ultraviolet-visible absorption spectrometry (UV-Vis), transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) methods were utilized for additional cha...
