The 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 کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولCatalytic Synthesis of Carbon Nanotubes and Nanofibers
Carbon nanotubes and nanofibers are graphitic filaments/whiskers with diameters ranging from 0.4 to 500 nm and lengths in the range of several micrometers to millimeters. Carbon nanofibers and nanotubes are grown by the diffusion of carbon (via catalytic decomposition of carbon containing gases or vaporized carbon from arc discharge or laser ablation) through a metal catalyst and its subsequent...
متن کاملPolysulfone/ Carbon Nanotubes Asymmetric Nanocomposite Membranes: Effect of Nanotubes Surface Modification on Morphology and Water Permeability
Polysulfone/carbon nanotubes (PSF/CNTs) nanocomposite membrane was prepared via phase inversion induced by immersion precipitation technique. In addition, the surface of the CNTs were functionalized by polar carboxylic and amine groups to improve the interaction between the CNTs and the polymer matrix. For this purpose, the neat CNTs were chemically treated using sulfuric acid/ nitric acid (H2S...
متن کاملCarbon Capture Using Amine-modified Carbon Nanotubes
The increasing rise in the rate of both anthropogenic CO2 emissions and atmospheric CO2 concentration, combined with an evolving understanding of what this means for global climate change both now, and in the future, has increased the need for novel technologies for CO2 capture from large point sources. Current industry standards involve the use of amine solvents, which have a large parasitic l...
