Abstract

A Ni/CeO₂/ZrO₂ catalyst with improved redox properties has been washcoated onto a honeycomb cordierite monolith in the form of a nonconventional alumina-catalyst layer, just a few nanometers thick. In spite of the very low active phase loading, the monolith depicts outstanding performance in dry reforming of methane, both in terms of activity, with values reaching the thermodynamic limit already at 750 °C, even under extreme Weight Hourly Space Velocities (WHSV 115-346 L·g^-1·h^-1), as well as in terms of stability during prolonged Time on Stream (TOS 24-48 h).

Keywords: FIB-(S)TEM; ceria-zirconia; dry reforming of methane; honeycomb cordierite; nickel.
