A series of inverse CeO 2 /Co 3 O 4 catalysts with different Ce loading was prepared via the hydrothermal process and microemulsion method, and characterized by XRD, BET, H 2 -TPR and TGA–DSC techniques. The catalysts exhibited high activity and moderate H 2 and CO selectivity for CH 4 /CO 2 reforming under atmospheric pressure and 750°C. The results showed that the CeO 2 /Co 3 O 4 catalysts with double pore distribution could provide more active sites as well as better gas circulation channels, which could reduce the internal diffusion resistance and improve the catalytic performance for CH 4 /CO 2 reforming.
