N2 - Ce0.5Zr0.5O2-d (CZ) with a high specific surface area and high oxygen storage capacity (OSC) was synthesized by a two-step hydrothermal process to obtain a flowerlike geometry, which can prevent the sintering of Ni under a reducing atmosphere. Durability tests on the prepared paper-structured catalysts (PSCs) for dry reforming of methane (DRM) at 750 C revealed that for both cases with and without CZ dispersion (Ni/CZ-PSC and Ni-PSC, respectively), the methane conversions were stable with degradation rates of 3.70% and 15.2% kh-1, respectively. After the one-week DRM test, the weights of the deposited carbon were 0.2 and 3.4 times those of the PSCs for Ni/CZ-PSC and Ni-PSC, respectively. Ni sintering and its detachment from the ceramic fiber that occurred in the Ni-PSC was solved by the dispersion of CZ (Ni/CZ-PSC) due to its unique morphology and high OSC.
