This document is an abstract for a conference paper that analyzes the shape-dependent catalytic properties of Au-Pt, Au-Pd, and Pt-Pd nanoparticles from a thermodynamic perspective. The paper studies how the face-centered cubic structure and shape of these transition metal nanoparticles impacts their stability and melting temperatures. It finds that tetrahedron and dodecahedron nanoparticle geometries result in the maximum and minimum variations, respectively, in transition temperatures for all three catalyst groups.

Abstract
Nanocatalysis is a very active field, so there are a few studies in the shape dependent
catalytic properties of transition metals from a thermodynamics approach. Transition
metal nanoparticles are very attractive due to their high surface to volume ratio. This
paper is a modest contribution to the ongoing discussions on the Au-Pt, Au-Pd and Pt-Pd
catalysts. The FCC structure of pt, Pd,Au has been considered in this model . The shape
stability of them has been discussed and size-dependent melting temperature of Au are
studied for the first time . The minimum and maximum variation of transition temperature
is related to tetrahedron and dodecahedron geometry for all three groups of catalysts.
