Fabrication and characterization of a novel TiO2 nanoparticle self-assembly membrane with improved fouling resistance

Ipomea carnea-based silver nanoparticle synthesis for antibacterial activity against selected human pathogens

“…The development of low fouling membranes or antifouling membranes is an intense area of research in membrane separation technology [27,28]. The use of nanoparticles in the manufacture of membranes allows for both a high degree of control over membrane fouling and the ability to produce desired structures [29][30][31]. In particular, AgNp-impregnated nanofibres and nanofibrillar aerogels can be used for antimicrobial membrane synthesis.…”

TiO2 immobilised on biopolymer nanofibers for the removal of bisphenol A and diclofenac from water

“…It has been reported that TiO 2 can absorb on polymers with -COOH group in two various schemes. One scheme is that TiO 2 can be bound with 2 oxygen atoms of COOH by a bidentate coordination to Ti 4+ cation and the other one that it can form hydrogen bonding between carbonyl group and the surface hydroxyl group of TiO 2 [33]. The additional functionality observed in the membrane after plasma treatment is due to the surface adjustment by grafting of hydroxyl, carbonyl, and carboxylate groups.…”

Waste Water Treatment Methods

“…Most attention has been given to TiO2 because of its high photocatalytic activity having a maximum quantum yields, its resistance to photo-corrosion, its biological immunity and low cost. There are two types of reactors: reactors with TiO2 suspended in the reaction medium and reactors with TiO2 fixed on a carrier material (Lim et al;2009, Mozia, 2010Li et al, 2009). A very promising method for solving problems concerning the separation of the photocatalyst from the reaction medium is the application of photocatalytic membrane reactors (PMRs), having other advantages such as the realization of a continuous process and the control of a residence time of molecules in the reactor (Mozia, 2010).…”
