Abstract

Abstract: The effects of temperature on the electrochemical behaviour of ferrocene and its derivative at a carbon fiber microelectrode were studied.By means of the noble feature of micro-electrode,and the temperature effect on currents,electrode potentials as well as heterogeneous electron transfer rate constant,a number of thermodynamic and kinetic parameters,such as E_al,D₀,k",ΔS",ΔG",ΔH",Q′_H and K,were determined.

Key words: Carbon fiber microelectrode, Temperature effect, Thermodynamic constant, Kinetic Parameter, Ferrocene and its derivative
