Subparticle catalytic properties of bimetallic vs monometallic regions. (A, B) The catalytic rate constant k (A) and reactant adsorption equilibrium constant K (B) of the bimetallic regions (Pd_Au, Au_Pd) vs monometallic regions (Pd, Au). Upper: results of individual nanoparticles; each dot is one PdAu nanoparticle. Lower: ensemble averages; error bars are SEM. (C, D) Scatter plots of k vs K for each type of region of individual PdAu nanoparticles; each dot is one region from one PdAu nanoparticle. ρ is Pearson’s cross correlation coefficient.
