In this study, fast gas adsorbent nanocomposites based on the carbon nanotubes (CNTs)/titanium dioxide (TiO2)/copper oxide (CuO)/Zeolite (CNTs/TiO2/CuO/Zeolite) and CNTs/TiO2 structures for nitrogen (NO2) removal have been investigated. The nanocomposite films were deposited glass substrate using push coating method. characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET). BET test was carried out to study total surface diameter of pores within matrices nanocomposites. For nanocomposite, NO2 concentration (NGC) decreased from 102 ppm 41 ppm, CNTs/TiO2/CuO/Zeolite NGC 172 34 ppm. results revealed that efficiency adsorption capacity 80 % 138 mg g−1, respectively with reduction rate K = 0.37 min−1. additional exhibited is higher than CNTs/TiO2.
