Direct synthesis of palladium nanoparticles on Mn3O4 modified multi-walled carbon nanotubes: A highly active catalyst for methanol electro-oxidation in alkaline media

► Excellent electrocatalytic activity and anti-COads poisoned ability toward methanol electro-oxidation in alkaline media. ► Increased catalytic activity is related to the Mn3O4 nanoparticles on the catalyst surface. ► Ea values demonstrated Pd-Mn3O4/MWCNT catalyst is more accessible reaction toward methanol electro-oxidation.
