Method for assembling atoms one-by-one into highly efficient multiatomic catalytic clusters.
About
One solution to improve catalytic efficiency while reducing precious metal usage is to build metal clusters from a “bottom-up” approach, by assembling individual atoms one-by-one, into multiatomic clusters. A stable organic semiconductor, polyaniline, as the isolation matrix is used to produce the atomic clusters, which can consists of few atoms of the same metal or atoms of different metals. Customizable atomic composition produces certain distinct chemical properties, which have followed theoretically predicted catalytic properties.
Key Benefits
Efficient: Atomic level catalyst dispersion to maximize available catalytic sites Controllable: Atomic control of cluster formation to generate pure metal and alloy catalysts of specific size and is scalable Economical: Minimal precious catalytic metal needed
Applications
Fuel cells (vehicle market, stationary and portable power, off-road applications, marine vessels, consumer electronics, direct fuel cells, etc.) Gas sensors (lower explosive limit, carbon monoxide, breathalyzer, oxygen, etc.).
