Elemental and structural behaviors of bimetallic nanoparticles under reactive environments and its implication in catalyst design, processing, and performance
Bimetallic nanocatalyst often shows enhanced performance where the key lies not only on the overall composition but more importantly, is related to the specific atomic arrangement of the two metal elements on the and near surface regions. In order to make the most out of bimetallic nanocatalyst, it …
