Catalysts are used in a variety of applications from the production of consumer goods to the protection of the environment. Optimum design and efficient utilization of catalysts requires a thorough understanding of the surface structure and surface chemistry of the active material.
Chemical adsorption (“chemisorption”) analysis techniques provide much of the information necessary to evaluate catalyst materials in the design and production phases, as well as after a period of use.
Although a catalyst and the reactants and products can be of many forms, this article addresses commonly used heterogenous catalysts.
