Graphite nanofibers (GNF) appear to be new and unique catalyst supports. A study was carried out to advance understanding of the unusual characteristics afforded by the GNF support from an examination of the behavior of this system concerning skeletal alkane reactions. Five percent platinum on a ″platelet-type″ GNF was active in skeletal reactions of n-hexane at lower temperature than Pt/SiO2. Turnover frequencies revealed maxima in both cases as a function of hydrogen pressure (p(H2)). Pt/GNF produced considerably more isomers than EUROPT-1 at lower temperature and higher p(H2). The selectivity of fragments was small, and their distribution exhibited almost perfectly random rupture. The propensities for both features could be elucidated by there being more surface hydrogen available with the nanofiber support. This combination may be a promising metal catalyst for low-temperature alkane isomerization reactions.
