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 measurement of magnetization is a highly informative technique for the kinetic studies of topochemical processes that occur during the preparation of supported metal catalysts for CO hydrogenation. The procedure of modifying a support (Al2O3) to decrease oxide-oxide interaction between the active component and support is proposed. The results of the study of topochemical processes during CO hydrogenation over Fe-, Co-, and Ni-containing catalysts are presented. The incorporation of carbon into the surface layer of a metal particle during CO hydrogenation over Co- and Ni-containing catalysts is shown.
