Boron-doped carbon nanotube-supported Pt nanoparticles with improved CO tolerance for methanol electro-oxidation.

Boron doping into carbon nanotubes improves the CO tolerance and increases the utilization efficiency of the supported Pt nanoparticles. Boron doping leads to a uniform deposition of Pt nanoparticles and also facilitates the removal of CO from the Pt surface, resulting in an increase in the electrocatalytic activity for methanol oxidation.
