Pore size distribution of carbon molecular sieves
Thread Content
I would like to ask what methods are generally used to measure the pore size distribution of carbon molecular sieves?
Carbon molecular sieves have a wedge-shaped microporous structure. There are specialized instruments for measuring the pore size distribution, specific surface area, and pore volume of microporous molecular sieves. Previously, when performing such type of characterizations, we used the ASAP-2020 microporosity analyzer from the American company Micromeritics.
