| Abstract: | The nickel hexacyanoferrate(NiCHF)film has been electrochemically deposited on glassy carbon (GC) electrode. After studying the effect of synthetic condition on thefilm cyclic voltammetry behaviour, combining with energy dispersive X-ray analysis (EDXtechnique,we described that the NiHCF film is composed of "soluble" K2NiFe(CN)6 and "insoluble" Ni2Fe (CN)6. By precisely controlling the deposition condition, we can obtain filmsdominated by either K2NiFe (CN)6 or Ni2Fe (CN)6. On the basis of these, we described theelectrochemical characteristics of the NiHCF film. |
