Highly dispersed Pt nanoparticles supported on high‐surface‐area 3D ordered macroporous (3DOM) Ce 0.6 Zr 0.3 Y 0.1 O 2 (CZY) are synthesized via a bubbling cetyltrimethyl ammonium bromide/P123‐assisted reduction route. The 1.1 wt% Pt/3DOM CZY catalyst shows supercatalytic activity for methane combustion, which is attributed to a higher oxygen adspecies amount, larger surface area, better low‐temperature reducibility, and unique nanovoid‐walled 3DOM structure.
