High-performance air cleaning membranes have been a research focus on efficient waste gas treatment, which is also the requirement of healthy living environment. In this paper, the current research progress of the carbon nanotubes (CNTs) membranes is systematically introduced. First, the chemical vapor deposition method experimental parameters the effect of the CNTs diameter and CNTs length are given a brief introduction. Different preparation methods of CNTs membranes based on different support materials such as inorganic fibers, electrospun fibers and ceramic supports are summarized in detail. Next, the multi-functional applications of CNTs-based membranes including ultrafine dust filtration, antibacterial and degradation of harmful gases such as VOCs, SO2 and O3 have also been reviewed, which indicates good prospective of CNTs-based membranes on multi-pollutants bearing air purification. Finally, the existed problems and the prospects of CNTs-based membranes are discussed.
