15 صفحه اولCarbon Nanofibers for Environmental Applications
Catalytically grown carbon nanofibers (CNF) are a newly developed type of material produced from the decomposition of selected carbon-containing gases over metal particles. These materials consist of nano-sized graphite platelets separated a distance of at least 0.335 nm and stacked in various orientations with respect to the fiber axis. Such an arrangement results in a unique structure that is...
متن کاملThe morphology, porosity and productivity control of carbon nanofibers or nanotubes on modified activated carbon
Since their discovery, carbon nanotubes and carbon nanofibers (CNTs or CNFs) have exhibited potential in a wide range of physical and chemical applications [1] and [2]. For applications in gas phase catalysis, loose CNTs or CNFs are unsuited because they limit the catalyst–reactant transport properties and they are difficult to handle when filling in the reactor tubes. In addition, there is a h...
متن کاملDesigning an ultrathin silica layer for highly durable carbon nanofibers as the carbon support in polymer electrolyte fuel cells.
A critical issue for maintaining long-term applications of polymer electrolyte fuel cells (PEFCs) is the development of an innovative technique for the functionalization of a carbon support that preserves their exceptional electrical conductivity and robustly enriches their durability. Here, we report for the first time how the formation of a partially coated, ultrathin, hydrophobic silica laye...
متن کاملAcid-base bifunctional catalysis of silica-alumina-supported organic amines for carbon-carbon bond-forming reactions.
Acid-base bifunctional heterogeneous catalysts were prepared by the reaction of an acidic silica-alumina (SA) surface with silane-coupling reagents possessing amino functional groups. The obtained SA-supported amines (SA-NR2) were characterized by solid-state 13C and 29Si NMR spectroscopy, FT-IR spectroscopy, and elemental analysis. The solid-state NMR spectra revealed that the amines were immo...
