Preparation and characterization of Pt-CeO2/C and Pt-TiO2/C electrocatalysts with improved electrocatalytic activity for methanol oxidation

- Adding TiO2 or CeO2 to Pt/C reduced its Pt particle size.
- Methanol oxidation current density decreased as Pt-CeO2/C > Pt-TiO2/C > Pt/C.
- Decreased Rct values were observed at Pt-TiO2/C and Pt-CeO2/C.
