“…The positively charged holes will also convert hydroxide ions to hydroxyl free radicals. It means all the species will finally be converted to hydroxyl free radicals (˚OH) which are the main agent in attacking the pollutant molecule and microorganisms in waste water and converting them to carbon dioxide, water, and mineral acids [78][79][80][81][82]. Photocatalytic process mainly takes place close to the surface of the semiconductor, and a high specific surface area is always demanded.…”

Separation using selective polymeric membranes has been well-established as an energy-efficient and cost-effective technology in water treatment and many other applications involving aqueous solutions. However, limited chemical, thermal, and mechanical resistances besides their tendency to fouling and inadequate pure water flux may often restrict their applications. To this end, inorganic materials as additives have been demonstrated to be able to enhance chemical, thermal, and fouling membrane resistances, which demonstrate their great potential for developing novel membranes by using them as additives in polymer matrices. Considering the excellent characteristics of the nano-sized particles, this study reviews the effects of inorganic nanoadditives on properties and performance of polymer/nanoparticle composite membranes. It has been demonstrated that using nanomaterials in a polymer matrix could enhance the mechanical strength and stiffness, wettability, selectivity, water permeability, and antifouling characteristics of the host polymer.

The water demand is predicted to increase by 50% over the next few decades [1].

“…In annular photoreactors, the water solution is confined between two concentric cylinders. Usually, the inner cylinder accommodates the light lamp, which is refrigerated with flowing air, although these reactors could be also externally irradiated [148]. This configuration provides a symmetrical irradiation and allows multiple possibilities for the positioning of the photocatalyst particles.…”

This review analyzes the preparation and characterization of metal organic frameworks (MOFs) and their application as photocatalysts for water purification. The study begins by highlighting the problem of water scarcity and the different solutions for purification, including photocatalysis with semiconductors, such as MOFs. It also describes the different methodologies that can be used for the synthesis of MOFs, paying attention to the purification and activation steps. The characterization of MOFs and the different approaches that can be followed to learn the photocatalytic processes are also detailed. Finally, the work reviews literature focused on the degradation of contaminants from water using MOF-based photocatalysts under light irradiation.

“…To overcome these disadvantages, slurry PMRs can be used. In these reactors, the photocatalysts particles are suspended in the aqueous phase, like in slurry reactors, and the membrane is used for the recovery/confinement of the photocatalysts particles [142,143].…”
