| Abstract | The advantages of using supported metal catalysts in preference to unsupported metals such as colloidal platinum or platinum black have long been appreciated. The support facilitates the formation of extremely small metal particles having a high proportion of their atoms a t the surface; the particles have rcniarkable thermal stability and the presence of the support allows the incorporation of beneficial additives, usually known as promoters. For many years supports were thought to be catalytically inert, except in the special case of bifunctional platinum-alumina catalysts for petroleum reforming. Recently there has ariscn evidence that in some systems at least the support can exert a marked influence over the properties of metal particles residing on it. When the platinum metals are supported on titania and reduced in hydrogen at 500°C they lose most of their ability to chemisorb hydrogen and carbon monoxide, and for certain reactions they also lose much of their catalytic activity. 'l'his has been attributed to a strong metal-support interaction (SMSI), and its discovery has awakened interest in the whole question of the nature of the interaction of metal particles with the support and with any promoters which may be present. The first International Symposium devoted specifically to this aspect of catalysis was held at Ecully, near Lyon, from the 14th to the 16th September 1 ~ 8 2 , and was organised by the Institut de Recherehes sur la Catalyse with financial support from the C.N.R.S. It was attended by some 180 persons from a number of countries including the People's Republic of China; six plenary lectures and thirty-five papers were presented during the three-day meeting. 'Two of the plenary lectures and at least twelve of the papers bore directly on the SMSI question. Rather than attempt to summarise each paper, it is perhaps better to identify their principal themes and to indicate thr current state of understanding of the problem by the use of selective examples. |
