Abstract:

The surface area and dispersion of a supported metal catalyst can be conveniently determined form the measurement of a chemisorbed monolayer of an appropriate adsorbate such as hydrogen at conditions under which little or no adsorption occurs on the support. Such measurements can be carried out by means of conventional high-vacuum-adsorption apparatus[1],but more rapid flow methods of measuring chemisorption are often found useful[2]. This is especially true when the need arises to characterize the multitude of catalyst samples generated by varying preparation, support, pretreatment and use of a given series of supported metals.
