Abstract

A method of turning a catalytic material by altering the charge state of a catalyst support. The catalyst support is intercalated with a metal ion, altering the charge state to alter and/or augment the catalytic activity of the catalyst material.

First claim

What is claimed is:

1. A method of tuning a catalyst comprising:
providing a catalyst support precursor having a catalytic metal bound thereto;
lithiating the catalyst support precursor with the catalytic metal bound thereto; and
altering the catalyst support precursor with the catalytic metal bound thereto by addition of a charge;
wherein the catalyst support precursor is selected from the group consisting of a lithium manganese oxide, a lithium titanate, and a nickel manganese cobalt oxide.

2. The method of claim 1 , wherein altering the catalyst support precursor comprises intercalation of a metal ion with the catalyst support precursor.

3. The method of claim 1 , wherein the catalyst support precursor is a ternary oxide.

4. The method of claim 3 , wherein the catalyst support precursor is selected from the group consisting of a lithium manganese oxide, a lithium titanate, and a nickel manganese cobalt oxide.

5. The method of claim 4 , wherein the catalytic metal is nickel.

6. The catalyst of claim 4 , wherein the catalyst support precursor comprises Ni y Li x Mn 2 O 4 , where y is 0.40 to 0.6 and wherein x is 0.48 to 1.12.

7. A method of forming a tuned catalyst material comprising:
providing a catalyst support precursor comprising a ternary oxide; binding a catalytic metal to the catalyst support precursor, the catalytic metal having a sub-monolayer on the catalyst support precursor, forming an untuned catalyst material; and
altering a charge state of the untuned catalyst material forming a tuned catalyst material.

8. The method of claim 7 , wherein altering the catalyst support precursor comprises intercalation of a metal ion with the catalyst support precursor.

9. The method of claim 8 , wherein the intercalation is lithiation.

10. The method of claim 9 , wherein lithiation includes exposure of an alkyl lithium reagent or an aryl lithium reagent.

11. The method of claim 10 , wherein the support is a lithium manganese oxide or lithium titanate.

12. The method of claim 7 , wherein the tuned catalyst material has exposed hydroxide groups of the catalyst support precursor.

13. The method of claim 7 , wherein the catalyst support precursor is a ternary oxide.

14. The method of claim 7 , wherein binding the catalytic metal is by a process selected from the group consisting of: grafting ligand abstraction, condensation, and protonolysis.
