This paper reports the newly designed 3D highly ordered macro/mesoporous multifunctional La1–xCexCoO3 nanohybrid frameworks with a 2D hexagonal mesostructure fabricated via facile meso-molding in a three-dimensionally macroporous perovskite (MTMP) route. The nanohybrid framework exhibited excellent catalytic activity for methane combustion, which derived from the MTMP providing a larger surface area and pore volume, uniform pore sizes, higher accessible surface oxygen concentration, better low-temperature reducibility, and a unique nanovoid 3D structure.
