a, b STEM images of Ptmet/Al2O3 (a) and Ptnon/Al2O3 (b) as well as the size distribution curves of the Pt particles (insets). c CO conversions as a function of temperature together with the extracted Ea (inset) over Ptmet/Al2O3 and Ptnon/Al2O3. d Schematic representation of two-half reactions coupling between two different active sites on one individual metallic particle or of the reaction without coupling occurring on isolated monoatomic active sites in CO oxidation. e, f STEM images of Rh1/Al2O3 (e) and Pt1/Al2O3 (f) and the atom-atom distance statistics (insets). g Ea values and TOFs of CO oxidation over Rh1/Al2O3 and Pt1/Al2O3 at 160 oC, which are obtained from Supplementary Figs. 29 and 30, respectively.
