Supported noble‐metal catalysts often suffer from nanoparticle sintering, resulting in rapid deactivation under high‐temperature conditions. We report hierarchically porous spinel type high-entropy oxide (S-HEO) nanofibers, (CrMnFeCoMg)₃O₄, as robust supports for Pt nanoparticles. The porous structure (38.5 m²/g) endows thermal stability, preserving porosity after 880 ℃ calcination. The porous Pt/S-HEO-500 exhibits exceptional sinter-resistance. Under 500 ℃ calcination, Pt exhibits only a 0.2 nm growth increment, owing to the physical confinement and strong metal–support interactions. For Pt/S-HEO-500, the T₅₀ (50% conversion temperature) for CO oxidation was merely 9 ℃ higher than that without calcination, with 100% conversion retained over 100 h of steady-state operation. These findings position porous spinel HEO nanofibers as a versatile platform for designing sinter-resistant noble-metal catalysts in high-temperature applications.
