An inverse opal‐structured Ni‐Co‐Mn/Al 2 O 3 catalyst with ultrahigh permeability was prepared by a sol–gel method templated by poly(methyl methacrylate) opal‐structured nanospheres. This catalyst exhibited excellent coke tolerance and a negligible reactor pressure drop in the dry reforming of methane. The highly permeable, unique macroporous structure allowed facile mass transport, which not only reduced the amount of coke deposition but also enhanced coke tolerance. Therefore, invariant CO 2 /CH 4 conversions despite substantial coke formation were observed.
