New Guide for Carbon Monoxide Chemisorption on Supported Platinum on Alumina Catalysts Using Dynamic Flow Method
1. Scope
A guide to enable the characterization of metal-supported catalysts by CO chemisorption using a dynamic flow technique.Keywords
Dispersion; Loading; StoichiometryRationale
The dynamic flow CO chemisorption method is most useful as a screening tool to measure relative dispersions of platinum on an alumina support. It may be extended to other supported metal systems provided that the user exercises care in optimizing the pretreatment and measurement conditions for the catalyst being tested. The method shall prove beneficial to users of metal-supported catalysts for research and quality control applications.
