Abstract

1. The chemisorption of O2 on Ni, applied on SiO2, is accompanied both by the oxidation of Ni and by the formation probably of a molecular form of chemisorbed O2. 2. The adsorption of H2 on a surface of Ni entirely covered with oxygen leads to the formation of H2O first according to the Rydil mechanism, and when adsorbed H atoms appear on the freed surface of Ni, according to the Langmuir-Hinshelwood mechanism. 3. The water formed in the first stages of the interaction of H2 with chemisorbed O2 diffuses from the surface of Ni and is chemisorbed on the surface of SiO2. The molecules of H2O formed in subsequent events of interaction are also adsorbed on the surface of SiO2 but are readily desorbed from it at room temperature.
