Enhance the selectivity of catalytic reactions is crucial for green chemistry to reduce chemical waste and achieve atom efficiency. Intermetallic compounds are solid-state mixtures of two or more metal components that possess ordered crystal structures. Compared to pure metals or random metal alloys, the crystalline structures and altered surface geometric/electronic structures could lead to superior properties of intermetallic catalysts in chemical transformations. Due to the exothermic formation process of intermetallic compounds, they are structurally more stable than random alloys and could maintain their ordered surface during catalytic reactions. Considering more than 100,000 reported intermetallic compounds of different compositions and structures, we only studied a very small portion of them in heterogeneous catalysis. In this talk, I will discuss one of the unique synthesis methods developed in my group, ship-in-a-bottle synthesis of monodisperse intermetallic nanoparticles. We will also discuss the superior catalytic properties of intermetallic nanoparticles, especially the enhanced activity and selectivity. Intermetallic nanoparticles, as unique catalysis platforms, will find applications in both fundamental researches and important industrial catalytic processes.
