Abstract
This work reports a new strategy toward the design of a new class of supported catalysts with intrinsic high-temperature stabilities through entropy maximization. The use of Pt, Ni, Mg, Cu, Zn, and Co not only enables the active sites to be highly dispersed for high catalytic activity in CO oxidation, but also results in extreme thermal stability (900 °C) owing to the entropy-stabilized behavior inside the metal oxide being able to survive harsh conditions.
