Adsorption of Gaseous Hydrogen onto Metal Surface

Abstract

Adsorption behavior of gaseous hydrogen on metal surface has been briefly reviewed, focusing on fundamentals for hydrogen entry that causes degradation of mechanical properties. The measurements for the adsorbed sites and states by means of thermal desorption spectroscopy and the work function are presented. Studies on the isotherm and adsorption kinetics are also presented. The effects of alloying elements and impurities on hydrogen coverage are summarized as well as the effects of gas components.
