Cobalt hexacyanoferrate particles were ground with water-miscible room-temperature ionic liquid, 1-methylimidazolium trifluoroacetic acidic salts (HMImTfa), and resulted in HMImTfa-CoHCF gel. The electrochemical properties of HMImTfa-CoHCF gel were investigated in detail. The impedance data show that HMImTfa-CoHCF gel is mixed ionic-electronic and has 2.5 times the improvement of the conductivity than that of pure HMImTfa. HMImTfa-CoHCF gel can be used in chemically modified electrode for the electrocatalytic oxidation of NADH. The corresponding results have important implications for the design of nano-structured and nano-composite materials based on water-miscible room-temperature ionic liquids, which could be used widely in chemo/biosensing and catalysis.
