A series of Cu-support systems were tested as potential candidates for DIR-SOFC (Direct Internal Reforming SOFC) catalysts towards a dry reforming of methane (DRM). The various supports (-Al2O3, CeO2, ZrO2, SrTiO3) with comparable specific surface area (SSA), and additionally -Al2O3 with SSA an order of magnitude larger than that of the other supports has been applied. The obtained Cu-support systems were characterized in terms of structure (XRD, XPS), microstructure (SEM), redox properties (TPR /TPOx), and next their catalytic activity and selectivity in DRM reaction were tested. All Cu-support materials show catalytic activity in DRM reaction, but only activity of Cu-SrTiO3 is high (due to the incorporation of Cu into SrTiO3 structure). The catalytic activity of other materials depends on the copper oxidation state (Cu2+ and Cu+). The highest catalytic activity in DRM process was obtained for Cu-AlO(OH) catalyst thanks to an order of greater SSA than in the case of other systems.
