Photoelectrochemical Properties of Oxide Systems Formed by Plasma Electrolytic Oxidation

详细

This paper describes the photoelectrochemical properties of titanium oxide formed by plasma electrolytic oxidation. The possibility of correlation between the photoactivity of the formed systems and their impedance characteristics was investigated. Equivalent circuitries which allow explanation of the character of the impedance spectra were constructed and interpreted. The role of heat treatment and surface modification with platinum on the photoelectrochemical and electrochemical characteristics of the formed systems was demonstrated.
