Research Methods

WithOleg V. Krylov, Boris R. Shub

Many concepts are used to characterize catalytic activity: the rate per unit of mass, volume, or catalyst surface area; the rate constant; and the so-called turnover number. One of the commonly used methods in surface science is the molecular beam method. It allows to investigate the energy exchange between molecules and surface, and to study the elementary stages of chemisorption and catalysis. One of the main advantages of the ion beam technique is its wide accessibility. The interaction of ions with solid surfaces has been a subject of study in many laboratories throughout the world for a long time. The fast development of laser technique has resulted in the appearance of a number of new research methods in the kinetic studies of the interaction of molecules with the surface. The pulsed lasers or catalysts with effective heat removal are used to avoid the thermal effects.
