In these Pt particles, more than 90% of atoms are located on the surface and the atomic coordination number of ∼1 nm particles is smaller than that in larger nanoparticles (e.g. 12 in a fcc lattice) which has a substantial fraction of the atoms in the bulk inducing distinctly different catalytic performance. |
