Material Brief: Nickel Catalyst – Active Metal Area and Dispersion – autosorb iQ C

A nickel catalyst supported on alumina was analysed using hydrogen gas on the autosorb iQ C and active metal area and dispersion were calculated from the measured static volumetric hydrogen isotherm.

The active metal area and percent dispersion are important properties for nickel catalysts. The larger the active metal area, the more efficient the catalyst will be in the reaction process. In addition, percent dispersion allows the researcher to determine how much of the added metal is available for a catalytic reaction. The higher the metal dispersion, the less metal is “wasted” during the catalyst synthesis.

The autosorb iQ C was used to measure hydrogen chemisorption on a nickel-on-alumina catalyst using a static volumetric measurement method.
