Dependence of mass transport behavior of NIHCNFe films in aqueous solution used in cyclic electrochemical quartz crystal microbalance (EQCM)

Abstract

The mass transport behavior during the redox reaction of NiHCNFe films in various cation-containing solutions has been studied using the cyclic electrochemical quartz crystal microbalance (EQCM) technique. It was found that hydrated cation transferred through the channel during redox reaction. It was shown that the number of accompanying waters depends on the nature and concentration of electrolyte solution. Especially, it was found that solvent transport is different in cesium electrolyte. Anion also seems to participate in NiHCNFe redox reaction, but its effect is different with regard to cation. It may be expected that lattice structure of NiHCNFe films related to mass transport moving into or out of the films during redox reaction.
