Carbon MWNT supported Pt catalysts; X. Wang, N. Li, L. Pfefferle, G. Haller

Yale University, Department of Chemical Engineering.

  • Carbon Multiwalled nanotubes (MWNT) allow stabilization of nm-sized Pt or Co particles for catalytic applications.

  • Binding energy changes for Pt particles inside (blue) and outside (red) the MWNT. Pt metal foil reference in black (see figure below).

  • This allows tuning of catalytic reactivity and selectivity (e.g. Wang et al. 2010).
