Query: The rise of Single-Atom Catalysts   In recent years, single-atom catalysts attracted lots of attention because of
their high catalytic activity, selectivity, stability, maximum atom
utilization, exceptional performance, and low cost. Single-atom catalyst
contains isolated individual atom which are coordinated with the surface atoms
of support such as a metal oxide or 2d - materials. In this review article, we
present the advancement in single-atom catalysis in recent years with a focus
on the various synthesis methods and their application in catalytic reactions.
We also demonstrate the reaction mechanism of a single-atom catalyst for
different catalytic reactions from theoretical aspects using density functional
theory.
