Abstract:
Catalysts prepd. by supporting Pt on SiO2 contg. low-valent ions of W have several specific features, in particular: (a) high Pt dispersion at redn. temps. up to 700°; (b) increased catalytic activity (both per gram Pt and per Pt surface atom) for hydrogenation of C6H6 and particularly for hydrogenolysis of C2H6; (c) decreased adsorption of H2 and CO on reduced catalysts. Some possibilities are considered in order to explain the exptl. data. The suggested model assumes the formation of surface species in which the clusters of metallic Pt are stabilized by interaction with low-valent W ions bound to the support.
