Abstract
Catalytic materials for use in carbon dioxide reduction reactions, such as during a dry reforming methane reaction or a reverse water gas shift reaction. The catalytic materials can include a MAX or MAX-LIKE phase material and a solid support. Also described are methods of performing a carbon dioxide reduction reaction using the catalytic materials and methods of preparing a catalytic material that includes a MAX or MAX-LIKE phase material.
Claims20
A catalyst for catalyzing the reduction of carbon dioxide, the catalyst comprising:
- a MAX or MAX-LIKE phase material having the chemical formula Mb+1AdJeXf,
- wherein M is a transition metal, A is an element from Group A, J is a dopant, and X is either carbon or nitrogen, and
- wherein b is either 1, 2, or 3;
- d is either 0, 1, 2, or 3;
- e is either 0, 1, 2, or 3;
- and f is either 1, 2, 3, or 4.
A method of performing a carbon dioxide reduction reaction, the method comprising:
- providing a catalyst, wherein the catalyst includes:
- a MAX or MAX-LIKE phase material having the chemical formula Mb+1AdJeXf, wherein M is a transition metal, A is an element from Group A, J is a dopant, and X is either carbon or nitrogen, and wherein b is either 1, 2, or 3;
- d is either 0, 1, 2, or 3;
- e is either 0, 1, 2, or 3;
- and f is either 1, 2, 3, or 4;
- and
- contacting the catalyst with carbon dioxide to reduce the carbon dioxide.
A method of preparing a catalyst, the method comprising:
- providing a MAX or MAX-LIKE phase material having the chemical formula Mb+1AdJeXf, wherein M is a transition metal, A is an element from Group A, J is a dopant, and X is either carbon or nitrogen, and wherein b is either 1, 2, or 3;
- d is either 0, 1, 2, or 3;
- e is either 0, 1, 2, or 3;
- and f is either 1, 2, 3, or 4;
- providing a solid support material;
- and
- securing the MAX or MAX-LIKE phase material to the solid support material to form the catalyst.
