During last few decades, membrane technology has emerged as an efficient technique over conventional methods due to its high removal capacity, ease in operation and cost effectiveness for wastewater treatment and production of clean water. Membrane based separations are commonly based on polymeric membranes because of their higher flexibility, easily pore forming mechanism, low cost and smaller space for installation as compared to inorganic membranes. Commonly employed membrane fabrication phase inversion method has been shortly reviewed in this article. Major limitation of membrane based separations is fouling and polymeric membranes being hydrophobic in nature are more prone to fouling. Fouling is a deposition of various colloidal particles, macromolecules (polysaccharides, proteins), salts etc. on membrane surface and within pores thus impedes membrane performance, reduces flux and results in high cost. Modification of polymeric membranes due to its tailoring ability with nanomaterials such as metal based and carbon based results in polymeric nano-composite membranes with high antifouling characteristics. Nanomaterials impart high selectivity, permeability, hydrophilicity, thermal stability, mechanical strength, and antibacterial properties to polymeric membranes via blending, coating etc. modification methods. Characterization techniques has also discussed in later section for studying morphological properties and performance of polymer nano-composite membranes. Graphical Abstract

“…The development of porous PVDF catalytic membrane by blending polymeric solution with Fe2O3 and multiwall carbon nanotubes (MWCNTs) provided good removal of humic acid using the catalytic oxidation of organic pollutants [15]. The porous catalytic membrane can be used in the degradation of organic contamination on the membrane surface and inside the pores by utilizing the oxidation power of generated hydroxyl radical [16,17].…”

“…However, immobilization of iron oxides likes Fe2O3 nanoparticles on the PVDF membrane to be used in dechlorination of trichloroethylene (TCE) at a near neutral pH; the TCE conversion reached to 100 % depending on iron and H2O2 ratio. Accordingly, the addition of nano-particles and metal oxides into polymeric membranes providing advanced treatment process by reducing the membrane fouling with subsequent cost savings with a merit for organic compounds degradation [15]. Figure 3 illustrates the inclusion of nanoparticles in the polymers by blending process.…”

“…Alpatova et al [15] prepared PVDF catalytic membrane by blending multiwall carbon nanotubes with Fe2O3 under sonication process. AFM testing of the prepared catalytic membrane was studied, which indicated that the addition of Fe2O3 has been slightly effected on the membrane surface roughness compared with the prepared membranes without any addition [15].…”

“…Alpatova et al [15] tested the contact angle of the prepared blend PVDF membranes with nanoparticles (multiwall carbon nanotubes with Fe2O3) and without nanoparticles. The results indicated that the PVDF membrane was a hydrophobic membrane with high contact angle (95.6±2.1 o ), while after nanoparticles addition the hydrophilicity of the membrane increased due to decrease in the contact angle below 90 o for all tested membranes [15].…”

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
