What is Ammonia Temperature Programmed Desorption (TPD)?
Ammonia Temperature Programmed Desorption (TPD) is an analytical technique commonly used in the field of catalysis to evaluate the acidity of catalytic materials. The method involves adsorbing ammonia (NH3) on the surface of a catalyst and then gradually increasing the temperature to desorb the ammonia. The amount and temperature of desorbed ammonia provide insights into the type and strength of acid sites on the catalyst's surface.
