New Test Method for Test Method for Carbon Monoxide Chemisorption on Supported Platinum on Alumina Catalysts using Dynamic Flow Method
1. Scope
Dynamic chemisorption is a commonly used technique for determining the active surface area of supported metal catalysts. The proposed method provides standard methodology for performing the preparation and chemisorption of carbon monoxide on supported platinum on alumina catalysts.
Keywords
chemisorption, platinum, alumina, carbon monoxide, dispersion, active, surface, area, pulse
Rationale
No standard exists for this technique. Active surface area determinations are widely used in the petroleum and chemical industries. Fule cell research also utilizes similar materials and requires dispersion and active surface area determinations.
The title and scope are in draft form and are under development within this ASTM Committee.
