“…[ 49,59–70 ] CuAg bimetallic catalysts are particularly important and reported to have increased conductivity, stability, and local concentration of surface carbon monoxide species (CO*). [ 15,16,36,43,65–68,70 ] Research on CuAg catalysts often relies on large nanoparticles (NPs, >30 nm), likely due to the challenges for making bimetallic NPs between two immiscible metals, highlighting the synthetic need and importance for controlling the atomic ratio and nanostructures between Cu and Ag towards generating active sites. [ 65–67,70 ] Strain effects of Ag atoms on the surface of CuAg nanocrystals may also promote multi‐carbon products.…”
