“…While many chemical methods have been extensively tested for ZnO nanoparticle synthesis, the NC-based composite approach seems to offer many promising features of green chemistry. For example, Nahi et al used NC extracted by the Tinospora cordifolia plant using simple sonication treatment as a template to synthesize ZnO . The ZnO–NC composite photocatalyst showed the enrofloxacin degradation efficiency of 97% after 120 min under sunlight irradiation.…”

Nanocelluloses (NC) are nature-based sustainable biomaterials, which not only possess cellulosic properties but also have the important hallmarks of nanomaterials, such as large surface area, versatile reactive sites or functionalities, and scaffolding stability to host inorganic nanoparticles. This class of nanomaterials offers new opportunities for a broad spectrum of applications for clean water production that were once thought impractical. This Review covers substantial discussions based on evaluative judgments of the recent literature and technical advancements in the fields of coagulation/flocculation, adsorption, photocatalysis, and membrane filtration for water decontamination through proper understanding of fundamental knowledge of NC, such as purity, crystallinity, surface chemistry and charge, suspension rheology, morphology, mechanical properties, and film stability. To supplement these, discussions on low-cost and scalable NC extraction, new characterizations including solution small-angle X-ray scattering evaluation, and structure− property relationships of NC are also reviewed. Identifying knowledge gaps and drawing perspectives could generate guidance to overcome uncertainties associated with the adaptation of NC-enabled water purification technologies. Furthermore, the topics of simultaneous removal of multipollutants disposal and proper handling of post/spent NC are discussed. We believe NC-enabled remediation nanomaterials can be integrated into a broad range of water treatments, greatly improving the cost-effectiveness and sustainability of water purification.

“…On other occasions, Nahi et al (2020) [ 115 ] reported the green synthesis of a visible-light-driven photocatalyst made from a zinc oxide/nanocellulose composite (ZnO/NC) for the photodegradation of Enrofloxacin (EF), an antibiotic commonly used in veterinary medicine to treat animals with bacterial infections. The incorporation of nanocellulose enhanced the bandgap to the visible region, allowing degradation of the EF under visible light.…”

Extensive research and development in the production of nanocellulose production, a green, bio-based, and renewable biomaterial has paved the way for the development of advanced functional materials for a multitude of applications. From a membrane technology perspective, the exceptional mechanical strength, high crystallinity, tunable surface chemistry, and anti-fouling behavior of nanocellulose, manifested from its structural and nanodimensional properties are particularly attractive. Thus, an opportunity has emerged to exploit these features to develop nanocellulose-based membranes for environmental applications. This review provides insights into the prospect of nanocellulose as a matrix or as an additive to enhance membrane performance in water filtration, environmental remediation, and the development of pollutant sensors and energy devices, focusing on the most recent progress from 2017 to 2022. A brief overview of the strategies to tailor the nanocellulose surface chemistry for the effective removal of specific pollutants and nanocellulose-based membrane fabrication approaches are also presented. The major challenges and future directions associated with the environmental applications of nanocellulose-based membranes are put into perspective, with primary emphasis on advanced multifunctional membranes.

In photocatalytic reactions, the fast recombination rate of photogenerated charge carriers limits practical application. So, in this study, a new g‐C3N4/Bi2S3/NiFe2O4 nanocomposite was synthesized with dual Z‐scheme heterojunctions to enhance charge carrier separation and visible light absorption. The structure, morphology, composition, magnetic, surface potential, and optical properties of the prepared g‐C3N4/Bi2S3/NiFe2O4 nanocomposite were investigated using XRD, FTIR, Raman, FESEM‐EDS‐Mapping, TEM, VSM, Zeta potential, PL, and UV–vis DRS techniques. Also, the photocatalytic performance and mechanism of enrofloxacin (Enro) and malachite green (MG) degradation under visible light were studied. Also, the photocatalytic performance and photodegradation mechanism were studied by enrofloxacin and malachite green degradation under visible light. The effect of the main parameters on the degradation performance of both pollutants was studied by response surface methodology (RSM). Under the optimum conditions, the highest photocatalytic degradation percentages for enrofloxacin and malachite green were obtained at 91.89% and 95.63%, respectively. The apparent rate constants of Enro and MG photodegradation over g‐C3N4/Bi2S3/NiFe2O4 were found to be 0.0628 min−1 and 0.0504 min−1, respectively. Based on its magnetic characteristics, the as‐prepared catalyst demonstrated facile recovery and good photocatalytic stability after six recycling studies, according to the results.
