Cobalt on carbon nanofiber catalysts:auspicious system for study of manganese promotion in Fischer-Tropsch catalysis

摘要

STEM-EELS and XPS investigation shows manganese oxide to be closely associated with cobalt nanoparticles supported on carbon nanofibers thereby improving selectivity in Fischer-Tropsch catalysis.Carbon nanofibers and carbon nanotubes,due to their small dimensions,large aspect ratio and tunable density,are a very promising material with a potential use in many applications.
