Abstract
Catalysts, particularly nanocatalysts, useful for converting carbon dioxide into desired conversion products, such as sustainable chemicals and fuels. The nanocatalysts may comprise at least one nanoparticle having a main component and a secondary component, wherein at least one of the main component and the secondary component facilitates the conversion of carbon dioxide. The present disclosure also relates to methods for preparing the nanocatalysts described herein and methods of using the same.
Claims8
A method for making a copper-copper nitride nanocatalyst nanoparticle comprising:
- providing a copper-alkylamine precursor complex, wherein providing the copper-alkylamine precursor complex comprises combining an alkylamine with copper acetate hydrate, copper (I) acetate, copper acetylacetonate, or a combination thereof;
- breaking a C—N bond of the copper-alkylamine precursor complex to provide a copper-copper nitride nanocatalyst nanoparticle comprising a copper component and a copper nitride component;
- and
- recovering the copper-copper nitride nanocatalyst nanoparticle, wherein:
- breaking the C—N bond comprises subjecting the copper-alkylamine precursor complex to an elevated temperature for a selected period of time, wherein the elevated temperature is from 160 to 240° C.,
- the copper component comprises copper from the copper-alkylamine precursor complex, and
- the copper nitride component comprises copper and nitrogen from the copper-alkylamine precursor complex.
