摘要：

Nanocomposites based upon ceria doped by Zr, Zr+La or Sm with supported Pt nanoparticles efficiently convert methane into syngas by their lattice oxygen. In red-ox cycles with pure methane as reagent, the surface carbon build-up is observed, which is lower for Sm -doped samples possessing a higher surface and lattice oxygen mobility. When stoichiometric amounts of CO2 or H2O are present in the feed, the catalysts efficiently operate in methane steam and dry reforming at high space velocities without deactivation.
