Abstract: This chapter reviews results of research aimed at design of catalysts of methane and biofuels transformation into syngas based upon perovskite-like oxides (doped ferrites –nickelates/(cobaltites) and manganese – chromates of La and Pr) and their nanocomposites with fluorites (YSZ, GDC) promoted by nanoparticles of Ni—based alloys (Ni-Fe, Ni-Ru, Co-Fe). The structural and surface characteristics of complex perovskite-like precursors (LnFe1-x-yNixRuyO3-z etc) and nanocomposites generated due to segregation of metal alloy nanoparticles from perovskites under reducing action of H2, CH4, and EtOH or reaction feed (CH4+ CO2; EtOH+ H2O, etc ) were studied by XRD, TEM with EDX, XPS. The oxygen bonding strength, mobility and reactivity were characterized by O2 TPD, H2/CH4/EtOH TPR followed by temperatureprogrammed reoxidation with H2O. Catalytic properties were estimated in reactions of CH4 dry reforming and ethanol steam reforming at short contact times. The most promising active components were supported on heat-conducting monolithic substrates and tested in concentrated feeds. Catalytic activity and coking stability of these catalysts were found to be controlled by the efficiency of reagents activation (fuel molecules –on metal sites, oxidants –on oxide support sites) and the surface/near surface oxygen diffusion to metal-support interface where activated C-H-O fragments interact with oxygen atoms generating syngas. Strong metal – oxide support interaction provides stability of metal nanoparticles to sintering in real operation conditions.
