BET Method for Surface Area Analysis SOLIDS

Dynamic Chemisorption and Temperature Programmed Reactions

The Brunauer-Emmett-Teller (BET) gas adsorption technique is the most com- monly used method for determining the surface area of nanomaterials. This course introduces the general theoretical fundamentals and techniques of this method, including a discussion of its strengths and weaknesses, and general guidance for its application. It trains users on sample preparation and pretreat- ment; instrument and software usage; data assemblage using nitrogen, krypton, argon, or carbon dioxide as probe molecules; and BET surface area and tex- tural properties determination of materials on the microporous and mesoporous ranges. Following this course, the user will be able to operate the instrument independently and perform basic data analysis.

Using gas or vapor as a surface probe, the chemisorption technique allows for the determination of important properties of a catalyst such as: percent of metal dispersion, active metal surface area, acid strength, surface acidity/basicity, estimated amount of coke deposited on catalyst after the reaction, determining metal oxidation state, and more. This course offers an introduction to basic prin- ciples, and exhaustive hands-on experience of the main instrument capabilities like dynamic pulse chemisorption, temperature programmed reduction (TPR), oxidation (TPO), desorption (TPD), and reaction analyses. It includes a detailed description of the instrument apparatus and its components, programming an experimental procedure and sequence, sample preparation and handling, run- ning various analysis methods (TPR, carbon monoxide or hydrogen chemisorp- tion, TPD-MS), TCD and MS detector calibration, data reduction, treatment, and interpretation. Following this course, the user will have gained the confidence to independently operate the instrument and perform basic data analysis.
