Carbon dioxide reforming of methane for syngas production over Co–MgO mixed oxide nanocatalysts

چکیده مقاله

Carbon dioxide reforming of methane (CH4 + CO2$2CO + 2H2) was studied over nanostructure Co– MgO mixed oxide catalysts with different cobalt contents. The catalysts were prepared by coprecipitation method and characterized using XRD, BET, TEM, TPR, SEM and TPO techniques. The BET analysis showed a high specific surface area and mesoporous structure (pore sizes < 15 nm) and the TEM analysis indicated a nanostructure with crystallite sizes smaller than 10 nm for the prepared catalysts. The obtained results revealed that the catalyst with cobalt content of 10 wt.% had the highest activity and stability in dry reforming reaction.
