No. 35 Measurement of Metal Dispersion of Cu-Supported Catalysts by N2O Pulse Measurement
BELCAT II
Introducing specific methods and precautions for measuring metal dispersion using the N2O pulse method!
The measurement of metal dispersion using CO or H2 pulse adsorption methods is a widely applicable technique for measuring the metal dispersion of various metal-supported catalysts. However, there are many metal-supported catalysts where the probe molecules CO and H2 do not adsorb, making the measurement of metal dispersion in those cases difficult. The N2O pulse method is a measurement technique that utilizes the oxidation reaction of surface metals rather than adsorption, and it can be used for catalysts that support metals that are relatively easy to oxidize (such as Cu). This document provides a detailed description of the specific methods and points to note regarding metal dispersion measurement using the N2O pulse method. We encourage you to read it.
