“…The utilization of bio-based materials as cost-effective and energy-efficient electrode materials for the purification of water has garnered substantial research interest. [148] Several methods including the impregnation of electrospinning mats, vacuum filtering, and direct deposition of a solution have been developed for fabricating bio-based membranes. For example, Huang et al created transparent lipid nanoporous membranes (TFN NFMs) by hydrolyzing microcrystalline cellulose nanocrystals with sulfuric acid.…”

Recent years have seen the emergence of capacitive deionization (CDI) as a promising desalination technique for converting sea and wastewater into potable water, due to its energy efficiency and eco‐friendly nature. However, its low salt removal capacity and parasitic reactions have limited its effectiveness. As a result, the development of porous carbon nanomaterials as electrode materials have been explored, while taking into account of material characteristics such as morphology, wettability, high conductivity, chemical robustness, cyclic stability, specific surface area, and ease of production. To tackle the parasitic reaction issue, membrane capacitive deionization (mCDI) was proposed which utilizes ion‐exchange membranes coupled to the electrode. Fabrication techniques along with the experimental parameters used to evaluate the desalination performance of different materials are discussed in this review to provide an overview of improvements made for CDI and mCDI desalination purposes

“…Because of its flexible nature for modification, biobased graphene can be tailored to enhance the way it performs in water treatment processes, especially its permeability, selectivity, and fouling resistance. 18 For uses where water quality is of utmost importance, including drinking water treatment, its biocompatibility resulting from natural sources makes it an appealing alternative. The fabrication of polymeric membranes uses plenty of toxic solvents such as N-methyl-2pyrrolidone (NMP) and N,N-dimethylformamide that are detrimental to the environment, 19 which can be minimized, if not avoided, by producing biobased graphene instead.…”

The growing demand for sustainable and renewable materials has driven extensive research into the use of lignocellulosic biomass as a promising feedstock for the development of advanced biobased membranes. In this present work, we established the viability of producing greener lignin-derived graphene oxide (bGO) and reduced graphene oxide (brGO) membranes from bamboo biomass to fabricate an ordered two-dimensional (2D) laminar channel for nanofiltration. It is imperative to emphasize that our methodology is intricately designed as a sequential strategy for the synthesis of bGO and brGO. This meticulously orchestrated sequence encompasses graphitization followed by consecutive oxidation and reduction processes, all unfolding prior to the subsequent facile layer-by-layer deposition, a pivotal step in membrane fabrication. The as-prepared bGO and brGO membranes showed nanosize pore openings of 1.15 and 0.03 nm and water pathway lengths of 65.15 and 49.09 nm, respectively. Pronounce enhancement by 52-to 60-fold in water permeance was exhibited using the brGO membrane for rejection of organic dyes (methylene blue, MB; direct red 81, DR-81) and salt (sodium sulfate, Na 2 SO 4 ) solutions compared to lignin-derived graphene oxide (bGO) membrane while the rejections remained comparable at 88, 99, and 57.6% for Na 2 SO 4 , MB, and DR-81, respectively. The brGO membrane's remarkable mechanical stability was also proven in an ultrasound test, withstanding up to 2 h without swelling and hence resistant to disintegration under solution immersion conditions. This work provides insight into the fabrication of graphene-based membranes from biomass for highly efficient nanofiltration performance and sheds some light on the transport mechanism within 2D laminar channels.

“…The materials require high absorbency, variable permeability, commercial viability, and recyclable qualities. Since the development of electrospun nanofibers, their potential benefits have spread to several academic disciplines [ 5 , 6 ]. The electrospun technique has received much attention as a novel way to make polymer nanofibers because it is straightforward to scale up and has a high production rate with ideal characteristics [ 7 ].…”

The effluents of industrial wastewater contain several toxic organic and inorganic pollutants that may contaminate clean and freshwater sources if untreated or poorly treated. These toxic pollutants include colors; hazardous compounds; surfactants; cosmetics; agrochemicals; pharmaceutical by-products; and agricultural, pharmaceutical, and medical contaminants. Treating wastewater has become a global problem. Many projects have been started in the last two decades to treat wastewater, resultant water pollution, and associated waste management problems. Adsorbants based on graphene oxide (GO) are viable wastewater treatment materials due to their adaptability, photocatalytic action, and capacity for self-assembly. Here, we report the fabrication of nanofibrous mats from polycaprolactone (PCL), carboxymethyl arabinoxylan (CMARX), and carboxyl-functionalized-graphene oxide using an electrospinning technique. The silver nanoparticles were loaded onto the mat to enhance their photocatalytic activity. These mats were characterized using different techniques, including Fourier transform infrared (FTIR), scanning electron microscope (SEM), and transmission electron microscope (TEM). The water contact angles were used to study their hydrophilic and hydrophobic behavior. The Langmuir isotherm model and adsorption kinetics were studied to evaluate their adsorption capabilities against methylene blue (MB). Sample 2 followed the Langmuir isotherm model (R2 = 0.9939). Adsorption kinetics exhibited pseudo-second order behavior (R2 = 0.9978) due to their maximum correlation coefficient values. MB has excellent adsorption at room temperature and the formation of the monolayer at the surface of the adsorption mat. An enhanced PO43− and MB adsorption was observed, providing recyclability up to 4–5 times. Hence, the fabricated nanofibrous mat would be a potential candidate for more effective wastewater treatment applications.
