Modification of electrochemical working electrode using NiO/MWCNT nanocomposites synthesized by microwave-assisted route

The modification of electrochemical working electrode using NiO/CNT nanocomposites was reported in this study. Nickel oxide/carbon nanotubes composites were prepared by chemically depositing nickel hydroxide onto carbon nanotubes under microwave irradiation and thermal annealing process. The as-prepared composites were characterized by Scanning Electron Microscopy and X-ray Diffractometer and the results indicated that NiO nanoparticles are well distributed on the surface of CNT. Current responses of the modified electrode using NiO/CNT nanocomposites demonstrated that the modified electrode with the composite prepared at 450 watt show the superiority in electrocatalytic activity.
