Cobalt-based Fischer–Tropsch catalysts supported on different types of N-doped carbon nanotubes

Abstract: N-doped nanocarbons are promising materials for metal-free and supported catalysts. Three types of N-doped carbon nanotubes (N-CNTs) were synthesized by chemical vapor deposition (CVD), by oxidation of the CVD produced N-CNTs with nitric acid, and by post-doping of oxidized undoped CNTs with ammonia. Cobalt catalysts with 20[Formula: see text]wt.% loading supported on N-CNTs were tested in the Fischer–Tropsch synthesis. Oxidized N-CNTs containing pyridone groups demonstrated the best stabilization of cobalt na… Show more

“…Of late, metal/metal oxide supported on an N-doped carbon matrix has evolved as a novel and efficient catalytic system because of its increased use in various industrially relevant reactions such as hydrodeoxygenation, dry reforming, hydrogenation, Fischer-tropes, dehydrogenation, C–C coupling, oxidative esterification, transfer hydrogenation, etc. Among various carbon matrices, reduced graphene oxide (RGrO) can be an excellent support material for various catalytic transformations due to its favorable high surface area. Further, nitrogen doping (N doping) of RGrO provides an excellent alternative for the dispersion of active catalytic metals on the surface, as the presence of N considerably influences the growth mechanism of metal nanoparticles as it generates potential binding/nucleating sites for the dispersion of active metals .…”
