Abstract

original image

All coated up: Platinum nanoparticles loaded on multiwalled carbon nanotubes (MWNTs) are coated with pyridine-containing polybenzimidazole (PyPBI). Interestingly, although a slight decrease in the accessibility of methanol is observed after coating, the methanol oxidation activity of Pt dramatically improves after coating with PyPBI.
