Abstract

Abstract: Cobalt hexacyanoferrate (CoHCF) microcrystallites exhibited well--defined cyclicvoltammetric waves in polyethylene glycol.The peak current of COHCF was linear to thescanning speed at 100 mV/s and lower.In-situ IR spectra indicated that the redox involvedinterchange of ferric and ferrous states of the hexacyanoferrate.CoHCF catalyzed the oxidation of ascorbic acid with the oxidation peak poteneial shifting negatively to 183 mV.Acatalysis mechanism is proposed.

Key words: cobalt hexacyanoferrate, polyethylene glycol, in-situ microscopic infrared spectroelectrochemistry, electric catalysis
