Comparison with other support media
Article Abstract:
The possible benefits of using graphite nanofibers as support media for metal particles used a hydrogenation catalysts were investigated. The research involved the hydrogenation of 1-butene and 1,3-butadiene implemented over a series of nickel catalysts at 80 degrees C and atmospheric pressure. The performance of nickel crystallites is assumed to be superior when it is scattered on graphite nanofibers compared to other conventional support materials. This superiority was shown through transmission electron microscopy because the metal was deposited evenly over the graphite nanofiber surfaces.

The influence of the nanofiber structure
Article Abstract:
Research was conducted to examine the catalytic behavior of graphite nanofiber supported nickel particles. The hydrogenation of simple alkenes and dienes including ethylene, 1-butene and 1,3-butadiene was used as probe reactions to monitor the possible changes in catalytic behavior induced by supporting nickel on three different types of nanofibers. Results indicate that when nickel is supported on graphite nanofibers, the system can exhibit some unusual patterns of behavior with respect to the catalytic hydrogenation of olefins and dienes.

The effect of chemical blocking on the performance of the system
Article Abstract:
A study was conducted to analyze the catalytic characteristics of graphite nanofiber nickel particles, with emphasis on the influence of chemical blocking on system performance. Results indicated that the active state of nickel correlates with the location of particles on the zigzag faces of the nanofiber structures. Findings also showed that the metal particles support a crystallographic arrangement that favors reactions with reactant molecules.
