Cobalt hexacyanoferrate (CoHCF) microcrystallites exhibited well-defined cyclic voltammetric waves in polyethylene glycol. The peak current of COHCF was linear to the scanning speed at 100 mV/s and lower. In-situ IR spectra indicated that the redox involved interchange 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. A catalysis mechanism is proposed.
- cobalt hexacyanoferrate,
- polyethylene glycol,
