• The effect of ZnO addition on cobalt–alumina interaction modes was studied using TPR and XPS. It was found that the addition of 2 wt% ZnO markedly affects the distribution of the cobalt species in CoO/Al<SUB>2</SUB>O<SUB>3</SUB> (5 wt% CoO): cobalt–alumina surface interaction species are removed and migration of cobalt into an alumina subsurface phase is promoted by ZnO. A formation of Co–Zn–O mixed oxide is proposed for ZnO–CoO/Al<SUB>2</SUB>O<SUB>2</SUB>O<SUB>3</SUB> at high ZnO content. The dispersion and distribution of ZnO on Al<SUB>2</SUB>O<SUB>3</SUB> are also strongly modified by the presence of cobalt.
