A simple and robust strategy is suggested for fabricating multifunctional hybrid separation membrane loading with catalytic nanoparticles based on the interception effect of porous CNTs network membrane. CNTs functionalized covalently with hydrophilic polyacrylic acid brushes assemble into a superhydrophilic/underwater superoleophobic network structure, which displays thickness dependent porosity. This allows the CNTs membrane capture catalytic nanoparticles by simple filtration process and construct flexibly desired separation membrane. Not only effectively separate oil-in-water emulsion, the prepared CNTs hybrid membranes can also catalytically decompose different organic pollutants in water by conveniently altering catalytic nanoparticles in the membrane. This robust construction provides a convenient means to obtain multifunctional CNTs separation membrane, promoting the practical application of superwettable CNTs membrane in the treatment of complex oily wastewater.
