The University of South Carolina is offering licensing opportunities for Metal oxide-metal catalysts using differential surface free energies.
Background:
One of the biggest problems with the manufacture of catalysts with multiple components is to position all of the components in proximal position in order to utilize the synergistic properties that result from cooperative interaction of the different components. The technology described in this disclosure uses thermodynamics, one of the basic forces of science and nature to drive the formation of multi-component catalysts with key components in the correct positions.
Invention Description:
This technology utilizes differential surface free energies of promotors and a metal element to position the promoters into proximal, adjacent positions in order to synthesize promoted catalysts. The promoters are diffused onto the top of the higher surface free energy metal particles, the extent of which are controlled by concentrations of the promoters and the temperatures. The resultant catalysts are superior compared to catalysts currently made and used.
Potential Applications:
This method could be used to form ethylene oxide, which is an important source of plastics, as well as ethylene glycol (antifreeze), polyurethane foam, and medicine production.
Advantages and Benefits:
This method of producing catalysts improves the selectivity to form ethylene oxide relative to formation of CO2, a greenhouse gas. Thus, in addition to using the expensive, feed gas ethylene more efficiently, it would lower greenhouse gas emissions
