Nano-sized Ag rather than single-atom Ag determines CO oxidation activity and stability
Single-atom catalysis recently attracts great attentions, however, whether single atom or their nanoparticle (NP) has the advantage in its intrinsic activity remains under heated debate. Ag/Al 2 O 3 is a widely used catalyst for many catalytic reactions, while the effect of Ag particle size on the a...

particle also accordingly decreases the concentration of surface active sites, hence, there is an optimum Ag

particle size. Our findings clearly confirm that Ag

nanoparticle has the advantage over single-atom Ag species in its intrinsic activity for CO oxidation. |
