Abstract
A catalytic carbon capture material is provided. The catalytic carbon capture material includes a microporous polymer including a Tröger's base moiety, and a transition metal is coordinated within the microporous polymer. The catalytic carbon capture material selectively captures carbon dioxide (CO2) and also is a catalyst that simultaneously converts the captured carbon dioxide into one or more carbon dioxide-based products. A method of making the catalytic carbon capture material and a method of selective carbon dioxide capture and conversion are also provided.
Claims14
A catalytic carbon capture material comprising:
- a microporous polymer including a Tröger's base moiety, wherein the microporous polymer is formed of:
- (i) one of 2,6-diaminotoluene or spirobi[fluorene] diamine precursors;
- and ii) dimethoxymethane precursors;
- and
- a transition metal coordinated within the microporous polymer;
- wherein the catalytic carbon capture material selectively captures carbon dioxide (CO2) and also is a catalyst that simultaneously converts the captured carbon dioxide into one or more carbon dioxide-based products.
