Single-atom
catalysts
(SACs)
exhibit
outstanding
catalytic
activity
due
to
their
highly
dispersed
metal
centers.
Activating
persulfates
(PS)
with
SACs
can
generate
various
reactive
oxygen
species
(ROS)
efficiently
degrade
emerging
organic
contaminants
(EOCs)
in
aqueous
environments,
offering
unique
advantages
such
as
high
reaction
rates
and
excellent
stability.
This
technique
has
been
extensively
researched
holds
enormous
potential
applications.
In
this
paper,
we
comprehensively
elaborated
on
the

We
also
analyzed
practical
considerations
for
application.
Subsequently,
discussed
