Abstract

The creation of a catalyst that can be used for a wide variety of applications including the steps of developing preliminary information regarding the catalyst, using the preliminary information to produce a template of the catalyst, and using the template of the catalyst to produce the catalyst.

Claims

1. A method of producing a catalyst for harvesting carbon dioxide from a gas mixture, comprising the steps of:

developing preliminary information regarding the catalyst for harvesting carbon dioxide from the gas mixture wherein said preliminary information includes potential energy surfaces around a metal center that will optimize reaction with carbon dioxide,

said step of developing preliminary information regarding the catalyst for harvesting carbon dioxide from a gas mixture including using molecule mimics wherein said molecule mimics are 1,4,7,10-tetraacyclododedacane and 1,5,9-triazacyclododedacane,

using said preliminary information for generating a selection of linking atoms that compose a scaffold on said metal center that will optimize reaction with carbon dioxide, and

using said preliminary information and said selection of linking atoms that compose a scaffold on said metal center to produce the catalyst for harvesting carbon dioxide from the gas mixture.

2. The method of producing a catalyst for harvesting carbon dioxide from a gas mixture of claim 1 wherein said metal center is a zinc metal center.

3. The method of producing a catalyst for harvesting carbon dioxide from a gas mixture of claim 1 wherein said metal center is a copper metal center.
