“…For example, nanocellulose/graphene composites have high adsorption, filtration and photocatalytic ability, and they are therefore widely used for water purification, e.g., for removing antibiotics [75], dyes [43], heavy metals, such as Cu 2+ , Hg 2+ , Ni 2+ and Ag + [61,76], or for their bactericidal effect [56]. The water-cleaning capacity of these composites can be further enhanced by introducing additional photocatalytic agents, i.e., palladium nanoparticles [54] or zinc oxide (ZnO) nanoparticles [73]. An optimized ultrafiltration membrane for water purification was constructed from polyvinylidene fluoride (PVDF), modified by cellulose nanocrystals functionalized with common bactericides, such as dodecyl dimethyl benzyl ammonium chloride, ZnO and GO nanosheets [129].…”

“…In addition to its advantageous combination with nanocarbon materials, nanocellulose is an appealing material for biomedical applications due to its tunable chemical fluorescence and luminescence [26,71,72] photothermal activity [56], hydrolytic stability [61], nanoporous character and high adsorption capacity [49,61]. Nanocellulose/nanocarbon composites can therefore be used in a wide range of industrial and technological applications, such as water purification [22,29,43,49,54,56,61,[73][74][75][76], the isolation and separation of various molecules [22,74,[77][78][79], energy generation, storage and conversion [21,23,44,47,64,[80][81][82][83][84][85], biocatalysis [86], food packaging [67][68][69]87], construction of fire retardants [48], heat spreaders [70] and shape memory devices [38,[88][89][90]. These comp...…”

Nanocellulose/nanocarbon composites are newly emerging smart hybrid materials containing cellulose nanoparticles, such as nanofibrils and nanocrystals, and carbon nanoparticles, such as “classical” carbon allotropes (fullerenes, graphene, nanotubes and nanodiamonds), or other carbon nanostructures (carbon nanofibers, carbon quantum dots, activated carbon and carbon black). The nanocellulose component acts as a dispersing agent and homogeneously distributes the carbon nanoparticles in an aqueous environment. Nanocellulose/nanocarbon composites can be prepared with many advantageous properties, such as high mechanical strength, flexibility, stretchability, tunable thermal and electrical conductivity, tunable optical transparency, photodynamic and photothermal activity, nanoporous character and high adsorption capacity. They are therefore promising for a wide range of industrial applications, such as energy generation, storage and conversion, water purification, food packaging, construction of fire retardants and shape memory devices. They also hold great promise for biomedical applications, such as radical scavenging, photodynamic and photothermal therapy of tumors and microbial infections, drug delivery, biosensorics, isolation of various biomolecules, electrical stimulation of damaged tissues (e.g., cardiac, neural), neural and bone tissue engineering, engineering of blood vessels and advanced wound dressing, e.g., with antimicrobial and antitumor activity. However, the potential cytotoxicity and immunogenicity of the composites and their components must also be taken into account.

“…The ZnO rod-ACF composite exhibited a high photocatalytic degradation of tetracycline in the first cycle (99%) and with cycles of utilization and regeneration the efficiency decreased due to the gradual loss of the ZnO from the ACF surface on cleaning. In another study, the nanoadsorbent-assisted photocatalytic degradation of ciprofloxacin was achieved through ZnO coupled with nano-cellulose and graphene oxide [264]. The coupling of ZnO with TiO 2 /clay nano architectures has also been documented to show better charge separation efficiency as well as narrowing of band gap [265].…”

Background: The limitless presence of pharmaceutical contaminants in discharged wastewater has emerged as a threat to aquatic species and humans. Their presence in drinking water has although raised substantial concerns, very little is known about the fate and ecological impacts of these pollutants. As a result, these pollutants are inevitably introduced to our food chain at trace concentrations. Unfortunately, the conventional wastewater treatment techniques are unable to treat pharmaceuticals completely with practical limitations. The focus has now been shifted towards nanotechnology for the successful remediation of these persistent pollutants. Thus, the current review specifically focuses on providing readers brief yet sharp insights into applications of various nanomaterials for the removal of pharmaceutical contaminants. Methods: An exhaustive collection of bibliographic database was done with articles having high impact and citations in relevant research domains. An in-depth analysis of screened papers was done through standard tools. Studies were categorized according to the use of nanoscale materials as nano-adsorbents (graphene, carbon nanotubes), nanophotocatalysts (metal, metal oxide), nano-filtration, and ozonation for promising alternative technologies for the efficient removal of recalcitrant contaminants. Results: A total of 365 research articles were selected. The contemporary advancements in the field of nanomaterials for drinking and wastewater treatment have been thoroughly analyzed along with their future perspectives. Conclusion: The recommendations provided in this article will be useful to adopt novel strategies for on-site removal of the emerging contaminants in pharmaceutical effluents and related industries.

“…The benefits of associating nanoscale photocatalysts with a complementary phase within composite structures have been demonstrated at several occasions [14]. In the case of ZnO-based nanocomposites, it can allow for a pre-concentration of the organic molecules at the vicinity of the photocatalysts, favor the dispersion of the photoactive phase and therefore increase the available reactive surface, permit shaping and recovery of the photoactive material, enhance intrinsic photocatalytic properties and lead to the design of multifunctional materials exhibiting magnetic properties or being able to degrade organics and retain toxic metals [15][16][17][18][19][20].…”

Zinc oxide-hydroxyapatite nanocomposites were prepared from a natural phosphate ore via a solvent-free method and evaluated for the photodegradation of two antibiotics in solution. The in situ growth of ZnO followed by thermal treatment allowed for the formation of photocatalytic nanocrystals homogeneously dispersed in the apatite phase. Nanocomposites exhibited higher rates of sorption of ofloxacin and ciprofloxacin compared to the individual phases. At high ZnO loadings, photodegradation performances of the nanocomposites under UV irradiation were equivalent or greater than that of the photocatalytic particles alone, depending on the considered antibiotic. This dependency reflects distinct degradation pathways that were attributed to different affinities of the antibiotics for the nanocomposite particles. Because of its simplicity and versatility, the here-described approach appears very promising for the development of multifunctional platforms for water remediation.
