“…In addition, the band around 893 cm -1 represents the stretching vibration of short Ti-O bonds involving non-bridging oxygen coordinated with sodium ions from sodium dodecylsulfate ions. Moreover, the peak observed at 1,598.7 cm -1 for PES/TiO 2 membrane was found to be shifted from the band given in the literature at 1,674 cm -1 [3,11]. This shift can be ascribed to interactions of TiO 2 with the sulfone group and ether bond in polyethersulfone structure.…”

“…Improvement of hydrophilicity and blood compatibility on polyethersulfone membrane occurred by blending sulfonated polyethersulfone to use as biomaterials [2]. Also polyethersulfone membrane's properties could be enhanced by using nanomaterials to use in water desalination [3][4][5][6][7][8]. Nano metal oxides have been mainly used for salt rejection% enhancement and fouling mitigation.…”

Abstract:In this work, PES (polyethersulfone)/TiO 2 nanotubes membranes were fabricated by a simple and cheap method. The TiO 2 NTs (titanium dioxide nanotubes) are prepared by the hydrothermal method, the tubes had a narrow size distribution with an average inner diameter of 3-5 nm and outer diameter of 10-13 nm. TiO 2 NTs blended PES membranes are prepared by phase inversion method with different nanotubes percentage (0.18%-0.85%). The morphology of PES membrane was obviously affected by the addition of TiO 2 NTs. The prepared membranes were applied on a vacuum desalination system and the desalination results showed that the salt rejection % and permeate flux of the membrane are enhanced through the addition of TiO 2 NTs. The membrane with higher (0.85%) TiO 2 NTs content resulted in a decrease of salt rejection % because of the defective membrane structure.

“…TiO 2 is favoured over other semiconductors due to its good physical and chemical properties, availability, photocatalytic activity, desirable hydrophilic and potential antifouling properties [5][6][7]. PES composite membrane modified by self-assembly of TiO 2 nanoparticles showed good separation qualities and higher water flux compared to the unmodified membrane, improved thermal stability, and increased hydrophilicity [2,8].…”

ABSTRACT. In this study, synthesized TiO2 nanorods and commercial Aeroxide P25 TiO2 nanoparticles were deposited on polyethersulfone (PES) membrane surfaces to compare their photocatalytic activity and effects on membrane surface and filtration properties. The catalysts were deposited on the membrane surface by physical deposition. The effect of the TiO2 amount on the stability of the catalyst layer and its effect on membrane resistance in presence and absence of UV irradiation were investigated. 1.2 mg/cm 2 catalyst coverage proved to be a minimal appropriate coverage to prevent membrane damage during UV irradiation. The catalysts formed hydrophilic layers on the surface, and in case of both catalyst the surface free energy increased compared to the neat membrane. The photocatalytic activity and retention of the modified membranes were tested spectrophotometrically by using Acid Red1, azo dye.

“…Generally, phase separation mechanisms can be subdivided into three main categories according to the parameters that induce demixing [10]. First, temperature-induced phase separation (TIPS) depends on changing the temperature at the interface of the polymer solution, where the heat can be exchanged and demixing can be induced.…”

The development of the chemical industry regarding reducing the production cost and obtaining a high-quality product with low environmental impact became the essential requirements of the world in these days. The catalytic membrane is considered as one of the new alternative solutions of catalysts problems in the industries, where the reaction and separation can be amalgamated in one unit. The catalytic membrane has numerous advantages such as breaking the thermodynamic equilibrium limitation, increasing conversion rate, reducing the recycle and separation costs. But the limitation or most disadvantages of catalytic membranes related to the high capital costs for fabrication or the fact that manufacturing process is still under development. This review article summarizes the most recent advances and research activities related to preparation, characterization, and applications of catalytic membranes. In this article, various types of catalytic membranes are displayed with different applications and explained the positive impacts of using catalytic membranes in various reactions. Copyright
