A nickel hydroxide platform prepared on a hydroxyl-enriched screen-printed carbon electrode for oxidative electrocatalysis

Abstract

We report here the preparation of an activation-free Ni electrode (i.e., eventually the formation of NiOOH) through enrichment of hydroxyl functional groups via a base-catalyzed hydrolysis reaction on a “preanodized” screen printed carbon electrode. The as-prepared Ni electrode exhibits good electroanalytic performance for the flow injection analysis of glucose.
