In order to further enhance the properties of polysulfone (PM membrane, such as hydrophilicity, antifouling and anti-compaction performance, sulfated TiO2 deposited on SiO2 nanotubes (STSNs) with super strong acid, tubular structure and high ratio of length to diameter were firstly prepared and then added to PSF to prepare STSNs/PSF composite membranes with micro-reaction locations (MRLs) inside channels and surface of membranes. STSNs and STSNs/PSF composite membranes were studied by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and contact angle of water, anti-compaction, respectively. The results show that the length of STSNs is 8 pm and the inner diameter is 300 nm, the ratio of length to diameter of SiO2 nanotubes is approximately 27; SiO42-/TiO2-SiO2 nanotube solid superacid is formed through depositing TiO2 nanoparticles on SiO2 nanotubes due to a stretching vibration peak of S=O double bond at 1300 cm(-1) in FT-IR spectra; the contact angle of STSNs/PSF composite membranes is declined from 76.5 degrees to 36.5 degrees. Compared with PSF membranes, SiO2/PSF membranes and phosphorylated Zr-doped hybrid silica (SZP)/PSF membranes, STSNs/PSF composite membranes show stronger anti-fouling and anti-compaction performance. Therefore. STSN/PSF composite membranes are desirable for treating wastewater containing oil. (C) 2015 Elsevier B.V. All rights reserved.
