Nanomaterial modified electrodes: evaluating oxygen reduction catalysts.
Intense current research is directed at the evaluation of nanomaterials as catalysts for the oxygen reduction reaction. This is commonly undertaken by means of voltammetric measurements supported on an electrode surface presumed inert other than for providing electrical contact. At their basis these factors usually involve measurement of a current or current density, measured at a fixed potential. However we now report that the current/current density at a fixed potential can vary with the su...Expand abstract
