Stabilized Pt Clusters
In article number 2300547, Yunqian Dai and co‐workers report that they effectively stabilize 2.6 nm‐Pt clusters against sintering over 800 °C on electrospun CeO2 nanofibers decorated by CeO2 nanocubes with thermodynamic and kinetic strategy. Such clusters show superior catalytic performance toward both the hydrogenation and oxidation reactions.
Sintering is a major concern for the deactivation of supported metals catalysts, which is driven by the force of decreasing the total surface energy of the entire catalytic system. In this work, a double‐confinement strategy is demonstrated to stabilize 2.6 nm‐Pt clusters against sintering on electrospun CeO2 nanofibers decorated by CeO2 nanocubes (m‐CeO2). Thermodynamically, with the aid of CeO2‐nanocubes,...
