the nanocomposite membrane includes a composite of carbon nanotubes coated or chemically bonded with metal oxide nanoparticles . this composite is embedded within a polymeric matrix via interfacial polymerization on a polysulfone support . the metal oxide particles are selected to exhibit catalytic activity when filtering pollutants from water in a water treatment system , or for separating a gas from a liquid , or for selectively separating particles or ions from solution for reverse osmosis , or other filtration requirements . a method of fabricating the nanocomposite membrane is also included herein .
