  • Abstract(Eng)
  • In this research, the Ir supported TiO2 (P25) catalyst was prepared by precipitation method for oxygen evolution reaction. The Ir/TiO2 catalyst was synthesised by reduction reaction using reducing agent. Physiochemical characterizations of synthesized Ir/TiO2 catalyst was studied by means of SEM, EDS mapping, TEM and XRD. The Electrochemical characterizations were tested by using the technique of CV and LSV by RDE and Potentiostat. Physicochemical properties were characterized with XRD where Iridium metal morphology and Ir(111) and Ir(222) peaks were founded. Ir0.2Ru0.8O2 exhibited higher OER activity than Ir0.5Ru0.5O2 followed by Ir/TiO2 and IrO2.
