Abstract
The present disclosure provides a composition. The composition includes a catalyst. The catalyst includes a mixed metal oxide support having a dendritic geometry and a metal coupled the metal oxide support.
Claims20
A composition comprising:
- a catalyst comprising:
- a mixed metal oxide support having a dendritic geometry;
- and
- a metal coupled the metal oxide support;
- wherein, when the catalyst contacts carbon dioxide and hydrogen, the catalyst produces a product stream comprising an unsubstituted straight or branched chained C5-15 alkane.

A method comprising:
- contacting a catalyst with carbon dioxide and hydrogen to produce a product stream comprising an unsubstituted straight or branched chained C5-15 alkane,
- wherein the catalyst comprises:
- a mixed metal oxide support having a dendritic geometry;
- and
- a metal coupled the metal oxide support.
2 more elements
A method comprising:
- adding a surfactant and a templating agent to a first solvent to produce a first solution;
- adding a silica precursor to the first solution to produce a silica support having a dendritic geometry;
- calcining the silica support having the dendritic geometry;
- impregnating the silica support having the dendritic geometry with a first metal salt and a second metal salt;
- calcining the silica support having the dendritic geometry with the first metal salt and the second metal salt to produce a dried product comprising a mixed metal oxide coupled to the silica support having the dendritic geometry;
- and
- contacting the dried powder with an etching agent, wherein the etching agent removes the silica support to generate a mixed metal oxide support having the dendritic geometry.
