Abstract
A simple electron transfer reaction followed by a homogeneous catalytic reaction is studied in this paper by three kinds of controlled convolution electrochemical experimental methods, which are the constant semi integral (CSI), linear semi integral sweep (LSIS) and linear semi differential sweep (LSDS). According to the three methods, the following equations can be obtained: CSI: πmΨ iI 1(τ)-1=ξe θ LSIS: π2bI 2(τ)-1=ξe θ LSDS: 3π8dI 3(τ)-1=ξe θ Where mΨ i=m i/nFAD 1/2 oC * o, b=D 1/2 ov/nFAk 02 C * o, d=cD 3/2 o/nFAk 04 C * o, m i, v and c are constant value of semi integral, sweep rate of semi integral and sweep rate of semi differential, respectively. With these equations, the theoretical curves of the above three methods can be computed. Experiments of the ferrocyanide ascorbic acid catalytic system have confirmed that kinetic rate constant in catalytic reaction is in good agreement with the previously reported values.
