中文摘要	ptru and pt nanoparticles were deposited on the surface of multiwalled carbon nanotubes (mwcnts) with the assistance of phosphomolybdic acid (pmo) by a one-pot hydrothermal reduction strategy. transmission electron microscopy shows a high-density ptru (or pt) nanoparticles uniformly dispersed on the surface of the mwcnts with an average diameter of 1.8 nm for ptru nanoparticles and 2.4 nm for pt nanoparticles. moreover, the as-prepared pmo/ptru/mwcnt and pmo/pt/mwcnt electrocatalysts are highly electroactive for the electrochemical oxidation of methanol. cyclic voltammograms show a high electrochemical surface area (esa) and a large current density for methanol oxidation at the modified electrode by pmo/ptru/mwcnt and pmo/pt/mwcnt electrocatalysts. electrochemical impedance spectroscopy reveals a high co tolerance for pmo/ptru/mwcnt and pmo/pt/mwcnt electrocatalysts in the electrochemical catalysis of methanol oxidation. for comparison, ptru/mwcnt and pt/mwcnt electrocatalysts were prepared in control experiments without pmo. the results demonstrate that ptru and pt nanoparticles deposited on mwcnts in the presence of pmo were superior to those on mwcnts without pmo in several respects including: (1) a smaller size and a higher dispersion; (2) a higher esa; (3) a larger current density for methanol oxidation; (4) a higher tolerance for co poisoning.
