BETporositeitsanalyse
BETporositeitsanalyse, also known as BET analysis, is a technique used to determine the specific surface area and pore size distribution of a material. The method is based on the adsorption of a gas, typically nitrogen, onto the surface of the material. The adsorption process follows the Brunauer-Emmett-Teller (BET) theory, which describes the multilayer adsorption of gases on solid surfaces.
The BET analysis involves several steps. First, the material is degassed to remove any adsorbed gases and
The pore size distribution is determined by analyzing the desorption branch of the adsorption-desorption isotherm. The
BET analysis is widely used in various fields, including materials science, catalysis, and environmental science. It
