Review on carbon nanotubes and carbon nanotube bundles for gas/ion separation and water purification studied by molecular dynamics simulation
Fatemi, S.M. & Foroutan, M.
Abstract
Water and air pollutants have huge impacts on
the entire living system. In addition, the newly emerging
nanopollutants, increasing global warming, and consequent
climate changes are posing major threats to the freshwater
or fresh air availability. This has made it urgent to invent
an appropriate water/air treatment technology that removes
nanopollutants and also desalinates water to a significant
extent. Carbon-based nanomaterials have generated marvelous
interest in a wide range of research activities due to
their high adsorption capacities. Carbon nanotubes, carbon
nanotube bundles, and related materials have potential
applications in gas/ion separation and water purification.
Recently, gas/ion separation and water purification through
carbon-based nanomaterials have received increasing
attention. This review summarizes the properties of carbon
nanotubes and carbon nanotube bundles related to gas
separation, ion separation, and water purification using
molecular dynamics simulations. Membranes-based carbon
nanomaterials show promise of water purification and gas
separation. These attractive properties of carbon nanotubes-
based and carbon nanotube bundles-based nanomaterials
make them proper candidates for gas separation,
gas molecular-sieving processes, and desalination purposes
in nanoscale dimensions.
