“…Polluted water treatments are challenging due to the high cost and cumbersome treatment processes involved. Several water treatments methods such as reverse osmosis (Liu et al, 2019), electrochemical means (e.g., capacitive deionization) (Han et al, 2019, Wang, Liu, et al, 2023, Zhang et al, 2022), and solar‐driven techniques (Li et al, 2021, Meng et al, 2023) have been reported and found to be effective. However, their high cost of operation limits among other setbacks their wide usage.…”

Increasing water pollution due to anthropogenic activities prompts the quest for an effective water treatment method. Polymeric materials have gained attention as adsorbents for water purification. Membranes are majorly made from homopolymeric materials. However, recent studies have focused on using copolymeric materials for improved performance. In this review, the basics of copolymerization including various types of copolymers, synthetic approaches, and their applications in various water pollutants removal are discussed in detail. Advances in water treatment technology using copolymeric materials as adsorbent/membranes in the last 4 years are covered with insights into the future outlook and areas of improvement in terms of copolymer composites for water treatment. Studies from the literature did not only reveal effectiveness of copolymer as a flocculant/antifouling materials and in removal of selective toxic metals, oil, and microbes but also demonstrated recyclability of the copolymer sorbents/membrane. Full exploration of unique copolymer textural and structural properties could lead to great advancement in water treatment process.Practitioner Points The copolymer types and synthetic methods are discussed. Application of copolymer as adsorbent/membranes for water treatment is presented. Recent advances show good pollutants removal for toxic metals, oil, and organics. Copolymer composites have great potential as adsorbent/membranes for future use in water treatment processes.

“…Excellent SAC (> 100 mg g À 1 ) as well as high ASAR (8.64-22.10 mg g À 1 min À 1 ) of the Bi-based RCDI devices signifies marvellous desalination performance (Table S2). Some recent attributes of the Cl À driven desalination are as follows: Wang et al [212] used Bi NCs@CNF electrode material in the symmetric RCDI cell, which showed SAC/ASAR as high as 102.26 mg g À 1 / 8.64 mg g À 1 min À 1 (constant current mode) in 3000 mg L À 1 NaCl solution and 92.9/89.2 % SAC/charge efficiency retention after 40 cycles. Fe/Fe 3 C nanoparticles decorated on N-doped graphene-like carbon (Fe/Fe 3 C@NGC) is used as a Cl À capturing electrode to assemble HCDI device (Cl À SAC/ASAR: 90.1 mg g À 1 / 1.50 mg g À 1 min À 1 at 1.4 V, Cl À SAC/ASAR: 101.1 mg g À 1 / 1.69 mg g À 1 min À 1 @ 0.03 A g À 1 , 70 % SAC retention after 60 cycles).…”

Capacitive deionization (CDI) of brackish water is emerging as a sustainable and energy efficient desalination processes to mitigate the excessive demand of freshwater. Despite that the porous carbon is prime choice in the conventional CDI; its electrostatic interaction‐based limited salt adsorption capacity (SAC, up to 25 mg g−1) has driven the research interest to explore various Faradaic electrodes for attaining maximum SAC (>100 mg g−1) in supplementation with the other desalination metrics. MXene is one of the newly discovered intercalation‐type pseudocapacitive nanostructures, which promised an excellent desalination performance due to its intriguing properties, such as tuneable interlayer spacing, high electrical conductivity, hydrophilicity, and structural integrity. Furthermore, its compositing/heterostructuring with other electro‐active components significantly improves the desalination activity. This article provides a systematic overview of the MXene‐based electrodes utilized in CDI along with the one‐to‐one comparison with other Faradaic systems. Materials design, structure, cell architecture, desalination metrics‐based performance evaluation, and underlying driving forces behind the salty ions removal activity are the main emphasis of discussion to realize MXene‐based efficient CDI desalination. Lastly, the key issues and perspectives of MXene‐based electrode systems are put forward towards new developments and real time implication.

Aerogels present a huge potential for removing organic dyes from printing and dyeing wastewater (PDW). However, the preparation of aerogels with multiple dye adsorption capabilities remains a challenge, as many existing aerogels are limited to adsorbing only a single type of dye. Herein, a composite aerogel (CG/T‐rGO) with the addition of carboxymethyl chitosan, gelatin and tannic acid reduced graphene oxide (T‐rGO) was synthesized by freeze‐drying technology. The electrostatic interactions between dye molecular and GEL/CMCS (CG) networks, as well as the supramolecular interactions (H‐bonds, electrostatic interactions and π‐π stacks) between T‐rGO, have endowed the aerogel with the ability to adsorb multiple types of dye, such as methylene blue (MB) and methyl orange (MO). Results exhibited that the prepared CG/T‐rGO aerogel possessed strong mechanical strength and a porous 3D network structure with a porosity of 96.33%. Using MB and MO as adsorbates, the adsorption capacity (88.2mg/g and 66.6 mg/g, respectively) and the mechanism of the CG/T‐rGO aerogel were investigated. The adsorption processes of aerogel for MB and MO were shown to follow the pseudo‐second‐order kinetic model and Langmuir isotherm model, indicating the chemical adsorption of a monolayer. The proposed aerogel in this work has promising prospects for dye removal from PDW.
