Why Is Catalyst Characterization Important?

Characterization is critical to the design and development of new catalysts, as well as process development and optimization (including scale-up and troubleshooting). For example, most heterogeneous catalysts are composed of catalytically active metals or metal oxides on the surface of metal oxide supports. Therefore, the structure and surface chemistry must be optimized to provide appropriate selectivity and reactivity for related processes. Other characteristics such as particle size, porosity, and surface area are also very important for optimizing diffusion and adsorption.
