Abstract
Official abstract text for this publication.
Described here is a graphene-catalysts conjugate, comprising: a graphene support; a first catalyst conjugated to the graphene support; and a second catalyst conjugated to the graphene support, and the second catalyst is different from the first catalyst. In some embodiments, the first catalyst and the second catalyst correspond to a tandem catalytic system to drive a chemical transformation.
