Static vs Dynamic Chemisorption: Insights from Platinum-Alumina Case Studies
Join Applications Scientist Phong Vuong in this webinar as he explores the metallic dispersion of Pt/Al2O3 supported catalysts using chemisorption of H2 and CO. Phong will compare static chemisorption results from the 3Flex with dynamic analyses from the ChemiSorb Auto, showcasing two case studies: one on the reusability of Pt/Al2O3 catalyst reference materials and another on the impact […]

The Effectiveness Of TPR For Catalyst Characterization
Introduction Chemisorption is a critical analytical technique used to investigate the surface properties of solid materials, particularly in the field of catalysis. Unlike physisorption, which involves weak van der Waals forces and is typically reversible, chemisorption involves strong, specific interactions such as covalent or ionic bonding. These interactions often result in the formation of a […]
Pulse Chemisorption For Evaluating Metal Dispersion AndCatalyst Activity
Introduction Chemisorption is a powerful analytical method used to investigate the surface properties of solid materials, particularly catalysts. Unlike physisorption, which involves weak van der Waals interactions, chemisorption involves strong interactions such as covalent or ionic bonds. This interaction is highly specific, often irreversible, and only forms a monolayer. The interaction highly depends on the […]

Introduction to Chemical Adsorption Analytical Techniques and their Applications to Catalysis
Abstract The chemical adsorption isotherm reveals information about the active surface of a material and has been employed for many years as a standard analytical tool for the evaluation of catalysts. Temperature-programmed reaction techniques have emerged from the 1950’s as an indispensable companion to chemisorption isotherm analyses in many areas of industry and research. This […]
Characterization of Supported Palladium, Hydrogen Sorption
Introduction The ASAP 2020 Chemisorption instrument can be used for many different analyses. One of the uses of the 2020 can be to analyze the chemisorption of hydrogen onto supported metal catalysts. In this study, 5 weight % palladium on activated carbon was used. During chemisorption, the bonds between H2 molecules dissociate on the metal […]
