Topochemical processes in CO hydrogenation catalysts

This article deals with topochemical processes in supported metal catalysts which are due to small sizes of reacting species. The continuous in situ m easurement of magnetization is a highly informative technique for the kinet ic studies of topochemical processes that occur during the preparation of s upported metal catalysts for CO hydrogenation. The procedure of modifying a support (Al2O3) to decrease oxide-oxide interaction between the active com ponent and support is proposed. The results of the study of topochemical pr ocesses during CO hydrogenation over Fe-, Co-, and Ni-containing catalysts are presented. The incorporation of carbon into the surface layer of a meta l particle during CO hydrogenation over Co- and Ni-containing catalysts is shown.
