June 22, 2016 - Micromeritics Workshop

Techniques for the characterization of texture, active surface area, and activity of powders and porous materials

Description

Topics for this one day workshop include surface area, porosity, and temperature programmed techniques. The characterization of texture, porosity, and surface area is presented along with the theory of measurement for both techniques. Textural characterization from Angstroms to millimeters will be discussed using the combination of adsorption and mercury intrusion porosimetry. In addition to textural characterization, chemical adsorption and temperature programmed methods will be used to characterize the activity of these materials.

Schedule

8:00 a.m. Registration Check-in
8:30 a.m. - 10:00 a.m. Adsorption and surface area- including the fundamentals of physical adsorption, classification of adsorption isotherms, and application of isotherm data to determine surface area.
10:00 a.m. - 10:15 a.m. Morning Break
10:15 a.m. - 11:45 a.m. External area and porosity - a standard isotherm (t-plot) method, condensation models (BJH and DH), and micropore techniques including NLDFT and HK methods will be discussed and their application to isotherm data for the understanding of micro and meso porosity (0.3 to 50nm).
11:45 a.m. - 12:45 p.m. Lunch
12:45 p.m. - 2:15 p.m. Characterization of macro and meso porous materials using mercury intrusion porosimetry. Mercury intrusion is a technique that is complimentary to gas adsorption and provides a method for characterizing materials with meso and macro porosity (3nm - 0.5 mm)
2:15 p.m. - 2:30 p.m. Afternoon Break
2:30 p.m. - 4:00 p.m. Chemical adsorption and temperature programmed techniques – selective (often referred to as chemical) adsorption is used to probe the active sites of a material. Temperature programmed techniques are commonly used to understand the oxidation state of the active species or the binding strength of the adsorbed species.
