Abstract

A planar model Co/SiO2 catalyst was prepared by depositing metallic cobalt onto silica films in ultrahigh vacuum conditions. CO hydrogenation was carried out at a total pressure of carbon monoxide and hydrogen between 0.33 and 1.0 bar. The effects of reaction temperature and pressure on kinetics and chain growth probability were investigated. The turnover frequency, activation energy, and product distributions were found in good agreement with those obtained on real catalysts. The formation of cobalt oxide or cobalt carbide was not observed after reaction.
