Abstract

4‐(3‐methyl‐1‐imidazolio)‐1‐butanesulphonic acid triflate (BSMIMOTF)–Nafion film is introduced as a novel catalyst support. Nafion is used as the conductive membrane for BSMIMOTF immobilisation. A uniform distribution of spherical platinum nanoparticles (PtNPs) 10–30 nm in diameter can be electrochemically deposited on the membranous BSMIMOTF–Nafion matrix. Compared with the PtNPs on a bare and Nafion‐modified electrode, the proposed sulphonyl‐terminated ionic liquid (IL)–Nafion stabilised PtNPs exhibit higher electrocatalytic activity and better stability towards the electro‐oxidation of methanol. The IL–Nafion film as a new catalyst support has great potential application in direct‐methanol fuel cells.
