Abstract:In supported catalysts, strong metal-support interaction (SMSI) is pivotal for modulating catalytic performance. Challenges, such as active site shielding and insufficient interfacial reactivity, have emerged as key points of attention. Here, we propose an amorphous encapsulation strategy creating permeable overlayers that preserve metal accessibility while maximizing metal-support interfaces. The engineered Pt@a-Nb2O5 catalyst is synthesized through a two-step process involving the heat treatment of the Nb2O5 support followed by wet chemical reduction.
