  • Title: Controllable pt nanoparticle deposition on carbon nanotubes as an anode catalyst for direct methanol fuel cells.
    Author: Mu Y, Liang H, Hu J, Jiang L, Wan L.
    Journal: J Phys Chem B; 2005 Dec 01; 109(47):22212-6. PubMed ID: 16853891.
    Abstract:
    We report a novel process to prepare well-dispersed Pt nanoparticles on CNTs. Pt nanoparticles, which were modified by the organic molecule triphenylphosphine, were deposited on multiwalled carbon nanotubes by the organic molecule, which acts as a cross linker. By manipulating the relative ratio of Pt nanoparticles and multiwalled carbon nanotubes in solution, Pt/CNT composites with different Pt content were achieved. The so-prepared Pt/CNT composite materials show higher electrocatalytic activity and better tolerance to poisoning species in methanol oxidation than the commercial E-TEK catalyst, which can be ascribed to the high dispersion of Pt nanoparticles on the multiwalled carbon nanotube surface.
