N2 - Paper-structured catalyst (PSC), consisting of the framework of inorganic fiber, can be applied on the anode of solid oxide fuel cells (SOFCs) to improve efficiency and stability of direct internal reforming SOFC (DIR-SOFC). Ni-loaded PSCs with the dispersion of ceria-based oxides were prepared by different processing routes. Using the prepared-PSCs, tests of dry reforming of methane (DRM) were performed at 750°C. Without the dispersion of ceria-based oxide, initial CH4 conversion and the degradation rate within 15 h were 86.2 and 7.7 %, respectively. With the dispersion of Ce0.4Zr0.6O2-δ (CeZ) having high oxygen storage capacity (OSC) prepared by co-precipitation, these were 87.5 and 3.2%, respectively. In the case with flowerlike-CeO2 (Ce(F)), despite the lower OSC than that of CeZ, these were 89.3 and 2.2%, respectively. Above results indicate that catalytic function (especially anti-coking property) of CeO2-based oxide particles derived from OSC can be further enhanced by controlling geometry of the particles.
