Pt nanoparticles ion-implanted onto indium tin oxide electrodes and their electrocatalytic activity towards methanol

► A versatile and green strategy for the fabrication of PtNPs onto ITO using an ion-implanted method. ► Small size PtNPs exhibits well catalytic performance and stability towards the electrooxidation of methanol. ► PtNP/ITO electrode may be a more suitable electrode material for the direct methanol fuel cell.
