Abstract

Embodiments of the present disclosure provide for methods of using Ni x Pt y nanoparticles, and the like. In an embodiment, a method of CO 2 reforming of methane is provided using supported Ni x Pt y nanoparticle material, wherein the Ni x Pt y nanoparticles have an average size of about 1.5 to 3 nm, wherein x is about 0.85 to 0.95 and y is about 0.05 to 0.15.

First claim

We claim at least the following:

1. A method, comprising:
providing supported Ni x Pt y nanoparticle material, the supported Ni x Pt y nanoparticle material comprising Ni x Pt y nanoparticles having an average size of about 1.5 to 3 nm, and wherein x is about 0.85 to 0.95 and y is about 0.05 to 0.15; and
using the supported Ni x Pt y nanoparticle material for CO 2 reforming of methane, by mixing and reacting methane and CO 2 and interacting the methane and CO 2 with the supported Ni x Pt y nanoparticle material serving as a catalyst for the reaction.

2. The method of claim 1 , wherein the average size of the Ni x Pt y nanoparticles is about 1.9 to 2.5 nm.

3. The method of claim 1 , wherein x is about 0.9 and y is about 0.1.

4. The method of claim 1 , wherein the Ni x Pt y nanoparticle material a functional nanomaterial.

5. The method of claim 1 , wherein the Ni x Pt y nanoparticles of the Ni x Pt y nanoparticle material are disposed on a support and the support is γ-Al 2 O 3 .

6. The method of claim 1 , wherein the Ni x Pt y nanoparticles of the Ni x Pt y nanoparticle material are disposed on a support and the support is selected from the group consisting of alumina, ceria, silica, titania, and activated carbon.

7. The method of claim 1 , wherein the method includes synthesizing nickel particles smaller than 5 nm and stabilizing their size throughout the reaction.

8. The method of claim 1 , wherein the Ni x Pt y nanoparticles of the Ni x Pt y nanoparticle material are disposed on a support and the support is selected from the group consisting of boehmite, TiO 2 , ZiO 2 , Ce 2 O 3 , and earth-alkali alumina spinels.
