“…Nowadays, the number of articles trying to remove pharmaceuticals from water with PMS is still not very high. In most of them, the degradation of tetracycline is the main topic [ 63 , 64 , 65 , 66 ], as it is considered one of the most widely used antibiotics today. Among them, the study of Liu et al (2022) [ 67 ] highlight the same positive effect of a catalyst (CoP/CoOx MOF) achieving practically total degradation in 15 min when a PMS concentration of 300 mg/L and 30 mg/L of a catalyst were used [ 67 ].…”

In this study, the removal of persistent emerging and dangerous pollutants (pharmaceuticals and pathogens) in synthetic wastewater was evaluated by the application of heterogeneous Advanced Oxidation Processes. To do that, a Metal-Organic Framework (MOF), Basolite® F-300 was selected as a catalyst and combined with peroxymonosulfate (PMS) as oxidants in order to generate sulphate radicals. Several key parameters such as the PMS and Basolite® F-300 concentration were evaluated and optimized using a Central Composite Experimental Design for response surface methodology for the inactivation of Escherichia coli. The assessment of the degradation of an analgesic and antipyretic pharmaceutical, antipyrine, revealed that is necessary to increase the concentration of PMS and amount of Basolite® F-300, in order to diminish the treatment time. Finally, the PMS-Basolite® F-300 system can be used for at least four cycles without a reduction in its ability to disinfect and degrade persistent emerging and dangerous pollutants such as pharmaceuticals and pathogens.

“…The unique physicochemical properties of g-C 3 N 4 polymer also enable it to function as an ideal membrane material. The moderate band gap of 2.7 eV enables it to absorb solar energy and photocatalyze dissociation of water to produce reactive oxygen species (ROS), which endows g-C 3 N 4 -based membranes with unique self-cleaning ability . The semiconductor properties of g-C 3 N 4 render it with the ability to drive the photocatalytic degradation process, whereas GO-based membranes do not have this function.…”

Membrane separation is a central area of research in chemical engineering because of its important status as the key technology in chemical separation and water treatment processes. Recently, polymeric graphitic carbon nitride (g-C3N4) has emerged as a candidate material for membrane applications because of its appealing physiochemical properties and ease of fabrication. Herein we review the progress of g-C3N4-based membranes, including the peculiarity of two-dimensional (2D) g-C3N4, the tailoring of functionality, and integration into membrane stacks for practical applications in gas separation, water purification, pervaporation, photocatalytic water filtration, oil-in-water separation, and polymer electrolyte membranes. Moreover, possible development directions of g-C3N4-based membranes are discussed along with the current challenges and future perspectives.

“…A new 2D bimetallic sulfide/N-doped reduced graphene oxide composite (FeCoS-N-rGO) was developed by self-assembling MOFs and GO nanosheets followed by carbonization and further sulfation, then a 2D/2D catalytic membrane (FeCoS-NGC) was fabricated by intercalating FeCoS-N-rGO into adjacent graphite carbon nitride (g-CN) [ 158 ]. In such a composite membrane, the permeation flux increased from 76 L·m −2 ·h −1 to 632 L·m −2 ·h −1 .…”

Every year the problem of water purification becomes more relevant. This is due to the continuous increase in the level of pollution of natural water sources, an increase in the population, and sharp climatic changes. The growth in demand for affordable and clean water is not always comparable to the supply that exists in the water treatment market. In addition, the amount of water pollution increases with the increase in production capacity, the purification of which cannot be fully handled by conventional processes. However, the application of novel nanomaterials will enhance the characteristics of water treatment processes which are one of the most important technological problems. In this review, we considered the application of carbon nanomaterials in membrane water purification. Carbon nanofibers, carbon nanotubes, graphite, graphene oxide, and activated carbon were analyzed as promising materials for membranes. The problems associated with the application of carbon nanomaterials in membrane processes and ways to solve them were discussed. Their efficiency, properties, and characteristics as a modifier for membranes were analyzed. The potential directions, opportunities and challenges for application of various carbon nanomaterials were suggested.
