Comparing static volumetric and pulse chemisorption
This brief compares results of four experimental combinations of probe molecules and adsorption processes and discusses advantages and disadvantages of each.
Hydrogen and carbon monoxide are the most commonly used probe molecules for selective adsorption on metal sites of heterogeneous catalysts. Such adsorption can be performed using static volumetric or flow chemisorption in pulses. This brief compares results from these four possible combinations and discusses some of the general pros and cons of each approach.
