Abstract

Ultraviolet and visible reflectance spectra were recorded in situ for oxidic and sulfided Moand/or Co-containing catalysts supported on alumina and silica. In addition, reflectance spectra of certain selected Mo and Co oxides and sulfides have been included for reference purposes. The results show the formation of MoS2 and Co9S8 in supported systems as a result of sulfidation in H2S/H2. The effect of oxygen chemisorption on sulfided CoO---MoO3/¿-Al2O3 and the effect of Co introduction on the MoS2 phase are discussed.
