Abstract
Provided herein are single atom catalysts embedded in carbon nanomaterials and microwave assisted methods of preparing the same.
Claims20
A method of incorporating at least one single atom transition metal catalytic site in a carbon nanomaterial, the method comprising mixing a metal-porphyrin complex with at least one carbon nanomaterial to form a mixture and subjecting the mixture to microwave irradiation.
A single atom catalyst comprising:
- a plurality of catalytic sites embedded in a holey carbon support, which comprises a plurality of nanoholes connected by nearly defect free graphene domains,
- wherein each of the plurality of catalytic sites independently comprises a transition metal center which is coordinated by four planar nitrogen atoms,
- wherein each nitrogen atom is bonded to the holey carbon;
- and
- each transition metal in each of the plurality of catalytic sites is not significantly aggregated with any other transition metal within the catalyst.
