Abstract
The CO2 methanation becomes promising solution to mitigate global warming and energy issues. Yttria-stabilized zirconia (YSZ) has been utilized for solid oxide fuel cell (SOFC) and solid oxide electrolysis cell (SOEC) applications. However, few researches about the use of YSZ as nickel-based catalyst support for CO2 methanation. Herein, we investigated the catalytic performance of 60wt%NiO-40wt%YSZ. The results showed that 60wt%NiO-40wt%YSZ produced methane with almost 100% selectivity and stable during more than 220 h. It confirms the excellent performance of 60wt%NiO-40wt%YSZ catalyst.
