A series of Ni/SBA‐15/Al 2 O 3 /FeCrAl metal monolithic catalysts with Ni loadings varying between 3 % and 16 % were prepared, and their structure was characterized by various techniques. The catalytic activity of the catalyst for methane reforming with CO 2 leading to synthesis gas was evaluated using a fixed‐bed reactor. The results indicate good catalytic activity of the Ni/SBA‐15/Al 2 O 3 /FeCrAl samples under the reaction conditions. The catalyst with a Ni loading of 8.0 % displays excellent activity and stability at 800 °C over 1400 h time on stream. After reaction, the hexagonal mesoporous structure of SBA‐15 is still present and the pore walls of SBA‐15 prevent the aggregation of nickel. Interactions between NiO, SBA‐15, and the Al 2 O 3 /FeCrAl support modify the redox properties of the Ni/SBA‐15/Al 2 O 3 /FeCrAl catalysts.
