Abstract
Supported, bimetallic catalyst systems are provided. The supported, bimetallic catalyst system can include a support defining a surface; a core metal positioned on the surface of the support; and a shell metal positioned on the core metal to form a core-shell particle on the surface of the support. The core metal has a surface free energy that is higher than a surface free energy of the shell metal. Methods are also provided for the formation of such supported, bimetallic catalyst systems, as well as the use of such supported, bimetallic catalyst systems in chemical processes.
Claims16
A supported, bimetallic catalyst system, comprising:
- a support defining a surface;
- a core metal positioned on the surface of the support, wherein the core metal is platinum;
- and
- a shell metal positioned on the core metal to form a core-shell particle on the surface of the support, wherein the shell metal is gold, and the core metal has a first surface free energy that is higher than a second surface free energy of the shell metal,
- wherein the core-shell particles cover at least 80% of the surface of the support.
