摘要: Abstract The electrode kinetics of [Ru(bpy)3]3+/[Ru(bpy)3]2+ (bpy = 2,2′-bipyridine) on a platinum was investigated in room-temperature ionic liquids, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA), 1-ethyl-3-methylimidazolium (EMITFSA), and bis(perfluoroethylsulfonyl)amide (BMPBETA) over the temperature range from 25 to 45 °C. diffusion coefficients [Ru(bpy)3]2+ [Ru(bpy)3]3+ were found be affected not only by viscosity liquids but also charge density complex. activation energy for these complexes close that liquids. standard rate constants BMPTFSA, EMITFSA BMPBETA estimated electrochemical impedance spectroscopy. smaller than those aqueous organic electrolytes, probably due slow dynamics
