raphene has attracted enormous interests due to its
potential applications in solid-state physics. Recently, it
has been shown that graphene can also be used as excellent
solid-state catalysts for various of chemical reactions, therefore
opening new opportunities for graphene applications in solid-
state chemistry. The pristine graphene itself is chemically quite
inert. Consequently, the central issue in graphene catalysis
is to activate graphene using practical physical or chemical
ways. Many ways have been proposed to enhance reactivity of
graphene such as doping graphene with metal impurity atoms,
applying a modest mechanical strain in graphene, creating
vacancy defects, and decorating graphene with functional
groups. However, the real applications of graphene solid-
state catalysts (GSSC) are still rather limited so far mainly due
to the fact that all those proposed methods require the direct
treatment of graphene, which is very difficult for large-scale
fabrication in a controllable manner. In this talk, we proposed
a promising new way of activating graphene: To activate
graphene by doping the underlying metal substrate with single
atom impurities or vacancies. In this way, the direct treatment
of graphene is no longer needed, therefore the large-scale
industry applications become possible. More interestingly,
the proposed method implies an unusual type of single-
atom catalysts. We expect the results presented to stimulate
new experiments and open new avenue for future design
and applications of graphene-based single-atom catalysts.
