Figure 4

Super-resolution catalysis imaging of PdAu nanoparticles with nanoscale gaps (gap-PdAu nanoparticles). (A) TEM image of gap-PdAu nanoparticles coated with mesoporous silica. Inset: a zoom in. (B) Box plot of the catalytic rate constant k of the proximal (Aup) and distant (Aud) Au hemispheres with regard to the Pd nanorods in the gap-PdAu nanoparticles. (C) Two-dimensional histogram of ∼2500 product locations on a gap-PdAu nanoparticle. White line: structural contours of the outer shell and the spherical Au particle. (D) SEM image of the gap-PdAu nanoparticle in C. Inset: zoom in of the nanogap.
