Abstract

Disclosed in certain embodiments is a catalytic material comprising: an active precious metal component comprising platinum; a sulfur-tolerant support material comprising silica on zirconia; and a substrate having the catalytic material coated thereon.

First claim

What is claimed is:

1. A catalytic material comprising:
an active precious metal component comprising platinum;
a sulfur-tolerant support material comprising silica on zirconia; and
a substrate having the catalytic material coated thereon, wherein the silica to zirconia ratio in the sulfur-tolerant support material ranges from 1:4 to 1:98.

2. The catalytic material of claim 1 , wherein the platinum is present in an amount from 0.4 wt % to 5.0 wt % of a total weight of the catalytic material.

3. The catalytic material of claim 1 , wherein the active precious metal component further comprises palladium, wherein the palladium is present in an amount of from about 0.1 wt % and up to 5.0 wt % of a total weight of the catalytic material.

4. The catalytic material of claim 1 , wherein the sulfur-tolerant support material is present in an amount from 90 wt % to 98 wt % of a total weight of the catalytic material.

5. The catalytic material of claim 1 , further comprising bulk ceria.

6. The catalytic material of claim 5 , wherein the bulk ceria is present in an amount from 0.5 wt % to 10 wt % of a total weight of the catalytic material.

7. The catalytic material of claim 1 , wherein the substrate comprises a ceramic material or a metal.

8. The catalytic material of claim 1 , further comprising a binder comprising one or more of silicon, zirconium, or aluminum.

9. The catalytic material of claim 8 , wherein the binder is present in an amount of from about 1 wt % and up to 10 wt % of a total weight of the catalytic material.

10. The catalytic material of claim 1 , wherein the catalytic material is in a form of particles, and wherein 90% of the particles of the catalytic material have a particle size ranging from about 6 micrometers to about 14 micrometers.

11. The catalytic material of claim 10 , wherein 90% of the particles of the catalytic material have a particle size of about 10 micrometers.

12. A catalytic system comprising the catalytic material of claim 1 .

13. A catalytic system comprising a catalytic material, the catalytic material comprising:
an active precious metal component comprising a mixture of platinum and palladium; and a substrate having a sulfur-tolerant support material coated on the substrate, wherein the sulfur-tolerant support material comprises a mixture of silica and zirconia, and wherein the silica to zirconia ratio in the sulfur-tolerant support material ranges from 1:4 to 1:98.

14. The catalytic system of claim 13 , wherein the platinum is present in an amount from 0.4 wt % to 5.0 wt % of a total weight of the catalytic material.

15. The catalytic system of claim 13 , wherein the palladium is present in an amount of from about 0.1 wt % and up to 5.0 wt % of a total weight of the catalytic material.

16. The catalytic system of claim 13 , wherein the sulfur-tolerant support material is present in an amount from 90 wt % to 98 wt % of a total weight of the catalytic material.

17. The catalytic system of claim 13 , further comprising bulk ceria.

18. The catalytic material of claim 17 , wherein the bulk ceria is present in an amount from 0.5 wt % to 10 wt % of a total weight of the catalytic material.

19. The catalytic system of claim 13 , wherein the substrate comprises a ceramic material or a metal.

20. The catalytic system of claim 13 , further comprising a silicon, zirconium, or aluminum based binder.
