Micropore Analysis
Pore Size Distribution, Pore Volume and Pore Area: Pores < 2nm diameter.
Micropores
are
generally
defined
as
those
smaller
than
2nm
diameter
and
are
common
in
a
range
of
materials.
For
example
carbons
and
nanotubes,
zeolites,
metal
organic
frameworks
(MOFs),
zeolitic
imidazolate
frameworks
(ZIFs),
covalent
organic
frameworks
(COFs)
etc.
Micropores
are
fundamentally
important
to
the
functionality
and
performance
of
many
applications,
such
as
battery
materials,
adsorbents
and
filters,
catalysts,
gas
storage
and
sequestration
materials.
Together,
micropore
volume,
area
and
size
directly
affect
performance
through
determining
capacity,
accessibility,
availability
of
active
sites
and
functionality.
For
many
applications
a
certain
micropore
size
range
is
demanded
in
order
to
maximise
performance.
If
pores
are
too
large
or
too
small
the
material
can
suffer
from
loss
of
capacity
and
activity
through
poor
retention
or
pore
blocking.
A
full
understanding
of
micropore
size,
area
and
volume
is,
therefore,
often
required.
At
MCA
Services
we
offer
a
range
of
micropore
characterisation
options.
Crucially,
dedicated
micropore
analysis
provides
a
full
set
of
pore
size,
volume
and
area
distribution
data
derived
from
specialised
data
reduction
methods,
such
as
DFT
(Density
Functional
Theory)
and
NL-DFT
(Non-Local
Density
Functional
Theory).
These
provide
consioderably
more
information
than
statistical
methods
such as t-plot, αS-plot and the Dubinin models. The can, however, also be applied if required to compare analyses with historical data.
Key Applications
Micropore size distribution, volume and pore area for:
Adsorbent capacity, accessibility and retention
Sequestration capacity, accessibility and retention
Gas storage capacity, accessibility and retention
Catalyst efficiency and activity
Battery efficiency, activity and charge & discharge ability
Filter efficiency and efficacy
Determination of regeneration conditions and efficiency
Investigations of atypical performance:
effects of low capacity and retention
Investigations of product failure: pore blocking
Identification of optimum characteristics and selection of materials
Determination of production and fabrication conditions
At
MCA
Services
we
use
the
latest,
state-of-the-art
Micromeritics
3Flex
instrument
for
micropore
analysis,
choosing
from
a
range
of
available
adsorbate
gases
and
applying
the
volumetric
method
for
the
measurement
of
adsorption
isotherms.
Analyses
can
be
confined
to
the
micropore
region,
typically
<
0.2
relative
pressure,
or
with
many
adsorbates,
extended
to
measure
data
in
the
mesopore
region.
Combined
micropore
and
mesopore
analyses
are,
therefore,
possible
in
a
single
analysis
and
extensive
data
reduction
and
reporting
methods
can
be
employed
to
characterise
each.
Nitrogen
is
most
commonly
used
as
the
adsorbate
with
excellent
results.
However,
when
unfavourable
interactions
between
nitrogen and the sample surface are likely, it is preferable to select an alternative adsorbate, such as argon.

data
interpretation:
selecting
the
most
pertinent
reporting
