Vertically aligned carbon nanotube membranes on macroporous alumina supports

Fabrication and Water Treatment Application of Carbon Nanotubes (CNTs)-Based Composite Membranes: A Review

“…Among various substrates, porous ceramic membranes in different geometries have been widely used to allow CNTs growth due to their excellent chemical, mechanical and thermal stability. Additionally, alumina (Al 2 O 3 ), yttria stabilized zirconia (YSZ), and mullite are the most commonly studied membrane materials [47,51,52,53,54,55,56,57]. Interestingly, randomly arranged or vertically aligned CNTs could be fabricated by different CVD conditions.…”

Synthesis and characterization of carbon nanotubes/poly vinyl alcohol nanocomposite membranes for dehydration of isopropanol

“…Acid treatment is an effective method for purification of the CNTs and opening their tips (removing deactivated catalyst particles). [42]. It is well known that CNTs inner cavities have remarkable smooth surfaces and as a result water molecules can slide through them readily [12,43].…”

Desalination across a graphene oxide membrane via direct contact membrane distillation

“…The synthesis of free-standing and silicon-supported vertically aligned CNTs membranes have been reported for reverse osmosis (RO) [11], and self-supporting bucky-paper membranes as well as interfacially polymerized bucky-papers have been used in MD [12]. Recently we have demonstrated the immobilization of nano carbons in different types of polymeric membranes to alter the solute-membrane interactions [13,14].…”
