Surface Phenomena Catalysis


The effect of the sulfiding temperature on the catalytic and structural properties of Co-Mo/Al2O3 catalysts is studied by taking into account the after-effects arising from 57-Co in the alumina. The catalytic activity is shown to be correlated to both MoS2 or CoMoS and Co9S8 phases.
