In
this
paper,
we
present
recent
results
of
our
attempts
to
produce
nanoporous
zirconia,
as
well
as
our
investigations
of
a
hybrid
material
consisting
of
nanoporous
zirconia
loaded
with
Ag-nanoparticles,
Ag-
n/ZrO
2
-NT/Zr,
which
could
be
used
as
an
active
SERS
substrate.
The
Zr-based
hybrid
material,
as
our
investigations
have
shown,
is
an
active
and
stable
substrate
in
SERS
investigations
aimed
at
detecting
various
organic
molecules:
mercaptobenzoic
acid,
pyridine
and
two
different
dyes
–
rodhanine
deriva-
tives.
The
SERS
spectra
for
the
probe
molecules
adsorbed
on
silver
nanoparticles
on
a
ZrO
2
-NT/Zr
platform
display
characteristic
intensity
ratios
different
from
those
measured
on
previously
studied
nanoporous
substrates
based
on
Ti
and
Al,
which
ensure
a
different
(alternative)
interaction
between
the
investi-
gated
adsorbate
and
adsorbent.
In
order
to
characterize
our
new
substrate
we
used
high-resolution
SEM
and
surface
analytical
techniques:
XPS
(X-ray
photoelectron
spectroscopy)
and
SERS
(surface
enhanced
Raman
spectroscopy).
