摘要：
CO adsorption on polycrystalline nickel was investigated by dynamic secondary ion mass-spectroscopy at 10−5–10−3 Pa and 300–500 K. An increase of secondary ion currents NiCO+/Ni+ ratio was found in the range from 300 to 350 K, while at T>350 K it decreased sharply. These data were explained by a kinetic model, in which adsorption and desorption of tightly bound CO goes through weakly bound CO formed due to ion-induced defects.
