Progressive Fabrication of a Pt‐Based High‐Entropy‐Alloy Catalyst toward Highly Efficient Propane Dehydrogenation

at 550 and 600 °C, respectively. Systematic characterizations reveal that the random elemental mixing, structural stability, and high Pt exposure promote the exposure of abundant stable isolated Pt sites. This work comprehensively explores the rational design and fabrication of HEA catalysts from a unique perspective, offering opportunities for developing advanced catalysts.
