Abstract
Polyoxometalate‐based

material
constructed
by
polyoxometalates
(POMs),

ions
or

organic
ligands,
are
combined

and

frameworks
(MOFs)

one
single
system.
This
integration
greatly
expands
their
potential
applications
compared
to
individual
MOFs.
Particularly
for
photocatalysis,

However,

limitation.
In

we
