The anodic response of glucose is compared for three Cu-based alloy electrodes (Ni10Cu90, Fe3Cu97 and Mn5Cu95) with that observed for a pure Cu electrode in the approximate potential region 0.00-0.80 V versus SCE in 0.10 M NaOH. Only the response at the Ni10Cu90 electrode is concluded to involve a redox-mediated mechanism based on voltammetric evidence for a surface redox process in the potential region of glucose response. The anodic response for glucose at the Mn5Cu95 electrode is significantly larger than that obtained for the other electrodes. This larger sensitivity at the Mn5Cu95 electrode is attributed to the kinetic benefit that results from preadsorption of glucose molecules at Mn-sites at the surface of the oxide-covered alloy electrode.
