Abstract

Nanoparticles comprising titanium, such as nanoscale doped titanium metal compounds, inorganic titanium compounds, and organic titanium compounds, their methods of manufacture, and methods of preparation of products from nanoparticles comprising titanium are provided.

Claims

1. A method for preparing a composition of matter comprising:

providing nanoparticles of a first composition comprising titanium; and

reacting the nanoparticles with at least one compound,

wherein the reacting creates a second composition of matter that differs from the first composition,

wherein the first composition further comprises at least three elements.

2. The method of claim 1, wherein the first composition comprises at least one oxide.

3. The method of claim 1, wherein the at least one compound comprises nitrogen.

4. The method of claim 1, wherein the at least one compound comprises at least one halogen containing compound or at least one silicon containing compound.

5. The method of claim 1, wherein the at least one compound comprises at least one acid or at least one alkali.

6. The method of claim 1, wherein the at least one compound comprises hydrogen.

7. The method of claim 1, wherein the at least one compound has a form chosen from solids, liquids, gases, and plasmas.

8. The method of claim 1, wherein the at least one compound comprises carbon.

9. The method of claim 1, wherein the at least one compound comprises oxygen.

10. The method of claim 1, wherein the second composition comprises carbon.

11. The method of claim 1, wherein the second composition comprises hydrogen.

12. The method of claim 1, wherein the second composition comprises nitrogen.

13. The method of claim 1, wherein the second composition comprises at least one organic substance.

14. The method of claim 1, wherein the second composition comprises at least one inorganic substance.
