Co@Pt (Co-core, Pt-shell) 4.10 nm sized particles supported on functionalized multi-walled carbon nanotubes (MWCNTs) have been synthesized and tested as efficient catalyst in direct methanol fuel cells (DMFCs). Catalytic activity and durability of all the catalysts for methanol oxidation (MO) have been studied in basic medium (0.5 M KOH) using cyclic voltammetry (CV). Chronoamperometry studies revealed that Co@Pt/MWCNTs has significantly high efficiency and stability than both Pt/MWCNTs and Co@Pt/MWCNTs catalysts. Mass activity exhibited by Co@Pt/MWCNTs for MO is 1.61 and 3.36 times higher than those of Pt.Co/MWCNTs and Pt/MWCNTs, respectively.

Keywords:Core.shell nanoparticles;Multi-walled carbon nanotubes;Cyclic voltammetry;Methanol oxidation;Direct methanol fuel cells
