Figure 1: Schematic illustration of the isolation of continuous bimetallic sites of alloy nanoparticle to SBMS.

From: Catalysis on singly dispersed bimetallic sites

Figure 1

Blue and yellow balls represent atoms of metal elements M and A. R1 and R2 are different reactants. (a) Schematic of a monometallic nanoparticle. (b) Schematic of a bimetallic nanoparticle. (c) Surface of an M–A bimetallic nanoparticle consisting of continuous bimetallic sites; R1 and R2 bind to A and M atoms, respectively. (d) Surface of an M–A bimetallic nanoparticle consisting of continuous bimetallic sites; however, R1 and R2 only bind to atoms of metal M instead of A; A is only the modifier of electronic or/and geometric structure. (e) Surface of an M–A bimetallic nanoparticle consisting of continuous bimetallic sites. (f) Isolated bimetallic sites anchored on a non-metallic support; different from the multiple binding configurations of R2 on an M–A bimetallic nanoparticle, here R2 can only bind to the single atom M through an on-top binding configuration.
