An extended X-ray absorption fine structure measurement was used to examine the structure of the oxide layers of the RuO2-IrO2/Ti electrode system and the thermal decomposition processes of RuCl3 and IrCls to form their respective oxides. Results showed that the heating of both chlorides causes them to decompose into their respective oxides. The coordination number of the oxide ions around the ruthenium and iridium ions increase with the calcination temperature. Moreover, the binary oxide system of RuO2-IrO2 forms a solid solution.
