Rational strategy for generating more active bimetallic PdAu nanocatalysts. (A) Correlation between the catalytic activity enhancement of the bimetallic Pd_Au region and the monometallic Pd region on the same heteronuclear PdAu nanoparticle. Each black dot is a single PdAu nanoparticle. Hollow red squares are binned and averaged results. The pure single Pd nanorods (pink) serve as the control. ρ is Pearson’s correlation coefficient for the individual particles. (B) Same as panel A, but for the bimetallic Au_Pd vs the monometallic Au regions with pure Au nanoparticles (pink) as the control. (C) The catalytic rate constant k of the side and end regions of Pd nanorods (average from 46 nanoparticles). (D) Schematic of the proposed strategy to deposit the second metal onto the ends of nanorods of the first metal. Error bars are SEM for all y-axes and SD for all x-axes.
