Abstract
Designing
3D
mechanically
robust
and
high‐surface‐area
substrates
for
uniform
high‐density
deposition
of
metal–organic
frameworks
(MOFs)
provide
a
promising
strategy
to
enhance

Nanofibrous
aerogel
(NFA)
with
its
porous
self‐supported
structure
composed
interconnected
nanofibrous
network
offers
an
ideal
platform
in
this
regard.
Herein,
facile
one‐pot
is
introduced,
which
utilizes
direct
MOF
on
the
NFAs.
NFAs
are
synthesized
using
electrospun

(PAN/PVP)
polymer
nanofibers
containing
zinc

),
subjected

thermal
treatment.
The
latter
converts
Zn(Ac)
oxide
(ZnO),
providing
sites

while
also
adding
mechanical
