Abstract
A nanocomposite catalyst includes a support, a multiplicity of nanoscale metal oxide clusters coupled to the support, and one or more metal atoms coupled to each of the nanoscale metal oxide clusters. Fabricating a nanocomposite catalyst includes forming nanoscale metal oxide clusters including a first metal on a support, and depositing one or more metal atoms including a second metal on the nanoscale metal oxide clusters. The nanocomposite catalyst is suitable for catalyzing reactions such as CO oxidation, water-gas-shift, reforming of CO2 and methanol, and oxidation of natural gas.
Claims16
A nanocomposite catalyst comprising:
- a support;
- a multiplicity of nanoscale metal oxide clusters coupled to the support;
- and
- 1-100 metal atoms coupled to each of the nanoscale metal oxide clusters,
- wherein the support is negatively charged, the nanoscale metal oxide clusters are positively charged, the 1-100 metal atoms are negatively charged, and the support is free of direct contact with the 1-100 metal atoms.
A method of fabricating a nanocomposite catalyst, the method comprising:
- forming nanoscale metal oxide clusters comprising a first metal on a support;
- and
- depositing 1-100 metal atoms comprising a second metal on the nanoscale metal oxide clusters,
- wherein the support is free of direct contact with the second metal.
