You can made CV experiments using a Potentiostate/galvanostate and 3 electrodes: working (i.e. platinum), reference (i.e. Ag/AgCl) and a counter (platinum wire). The experimental conditions, for example voltage range, scanning rate, sample concentrations and solvent, and support electrolite, will depend on your sample. We have a Gamry 300 and it is useful for some semiconducting materials, which present electrochemical activity. If you need to use it, you can send me your sample.
CV tests are performed by potentiostat using three-electrode system electrochemical cell. These electrodes are working, reference and counter electrodes. Common reference electrodes are calomel and Ag-AgCl electrodes. Pt-wire of Pt-foil can be employed as counter electrode. Working electrode may be Pt-wire or solid examined material. Surface area of working electrode should be known to determine current density. Supporting electrolyte should be conductor. Oxygen can be removed from supporting electrolyte by bubbling nitrogen or argon. Detailed information can be found in web.
