- The catalytic partial oxidation (CPOx) of methane is an attractive source of H2 and CO for fuel cell applications. However, the deposition of carbon onto the surface of the catalyst and the migration and loss of active metals remain the principal issues in the development of a suitable catalyst. The formation of elemental carbon onto the surface of a catalyst has been shown to be related to both the size of the active metal cluster  and its coordination . The substitution of a catalytic metal into the lattice of hexaaluminate compounds may serve to reduce the size of active metal clusters and to increase their dispersion thereby reducing their susceptibility toward carbon deposition. Interactions between neighboring substituted metals and the hexaaluminate lattice may serve to suppress active metal mobility. In the present work, a series of barium hexaaluminate catalysts with Ni substituted into the lattice were prepared with the general formula, BaNiyAl12-yO19-δ (y = 0.2, 0.4, 0.6, 0.8 and 1.0). The temperature programmed activity and selectivity for this series were investigated.
