【Abstract】 The flat-potential of different tandem semiconductive anode can be acquired by means of alternating impedance technique and electrochemical method.So the largest theoretical photovoltage was achieved to offer primary data for optimizing the preparative parameter.The photocorrosion can be inhibited effectively when dissolving different oxidation-reduction electrocouple in lithium perchlorate-acetonitrile non-aqueous solution.The results indicate that the tandem semiconductive material with narrower band-gap covered with that of wider band-gap can avoid or inhibit the photoetch.更多还原
