Abstract
Covalent
organic
frameworks
(COFs)
feature
π‐conjugated
structure,
high
porosity,
structural
regularity,
large
specific
surface
area,
and
good
stability,
being
considered
as
ideal
platform
for
photocatalytic
application.
Although
single
COFs
have
achieved
significant
progress
in
photocatalysis
benefiting
from
their
distinctive
properties,
the
COFs‐based
hybrids
provide
an
extraordinary
opportunity
to
achieve
superior
performance.
From

a
systematic
summary
based
on
other

materials
(metal
atoms,

frameworks,
polymers)

In
