Abstract

The electrochemical oscillation behaviour of hydrogen peroxide cathodic reductionprocess on the electrodeposited silver indium selenide electrode has been studied by using in-situdynamic impedance and the condensance measurement technique in different supporting electrolytessolutions.The surface composition of AglnSe_2 electrodes(before and after oscillating)were also givenby AES. According to the experimental results,the influence of Cl ̄- on the mechanism of thiselectrochemical oscillaton process has been discussed in detail.
