چکیده
An overview of the synthesis and characterization of several Pt-Ru or Pt-MoNulcan carbon nanocomposites and one Pt-Rdgraphitic carbon nanofiber nanocomposite is provided. Each binary metal alloy nanocluster composition is accessed through the t h d decomposition of a single-source molecular precursor containing the desired metal stoichiometry. Microwave heating techniques are. used to form a Pt-RuNulcan carbon nanocomposite within,one minute of thermal treatment. The metal stoichiometry of individual alloy nanoparticles has been determined from onparticle EDS measurements obtained using HR-TEM(FEG) instrumentation. Preliminary DMFC testing results are. also summarized.

Pt-Ru supported on double-walled carbon nanotubes as high-performance anode catalysts for direct methanol fuel cells.
Pt-Ru supported on carbon nanotubes (CNTs) (single-walled nanotubes, double-walled nanotubes (DWNTs), and multi-walled nanotubes) catalysts are prepared by an ethylene glycol reduction method. Pt-Ru nanoparticles with a diameter of 2-3 nm and narrow particle size distributions are uniformly deposited onto the CNTs. A simple and fast filtration method followed by a hot-press film transfer is emp...
متن کاملEffect of Pt on Zn-Free Cu-Al Catalysts for Methanol Steam Reforming to Produce Hydrogen
Steam reforming of methanol can be considered as an attractive reaction aiming at hydrogen production for PEM fuel cells. Although Cu/Al-contained catalysts are considerably evaluated in this reaction, further evaluation is essential to evaluate the impact of some promoters like Pt in order to find a comprehensively optimized catalyst. Pt promoter is employed with different methods in this ...
