In recent years, metal‐organic frameworks (MOFs) are attracting increasing attention due to their charming properties. However, the intrinsic fragility, powdered crystalline state, and poor processibility of MOFs hinder their further application. By this, the designs of MOF‐based aerogels, hydrogels, membranes are effective ways to solve this problem. Graphene, silica, synthetic polymer and cellulose are the commonly used raw materials for fabricating MOF‐based aerogels, hydrogels, and membranes. Among them, cellulose and its derivatives are the best candidates to support the powdered MOFs from the perspectives of economy, environmental protection and property. This review focuses on discussing the advantages of MOF@cellulose hybrids in applications such as water treatment, antibacterial, gas separation and adsorption, energy storage, drug delivery, catalysis, and other smart composites. MOF@cellulose‐based aerogels, hydrogels and membranes can provide valuable guidance for investigating the practical application of MOFs in terms of processability, reusability, stability and easiness in handling.

“…Apart from lower toxicity, it is also important to determine to what extent solvent change can affect the performance of the membrane. Prihatiningtyas et al [ 74 ] compared the membrane desalination performance of DMSO to several traditional solvents which are NMP, DMF and dioxane. Cellulose nanocrystals (CNCs)-incorporated cellulose triacetate (CTA) membranes were successfully fabricated via dope casting in different solvents.…”

Water constitutes one of the basic necessities of life. Around 71% of the Earth is covered by water, however, not all of it is readily available as fresh water for daily consumption. Fresh water scarcity is a chronic issue which poses a threat to all living things on Earth. Seawater, as a natural resource abundantly available all around the world, is a potential water source to fulfil the increasing water demand. Climate-independent seawater desalination has been touted as a crucial alternative to provide fresh water. While the membrane-based desalination process continues to dominate the global desalination market, the currently employed membrane fabrication materials and processes inevitably bring adverse impacts to the environment. This review aims to elucidate and provide a comprehensive outlook of the recent efforts based on greener approaches used for desalination membrane fabrication, which paves the way towards achieving sustainable and eco-friendly processes. Membrane fabrication using green chemistry effectively minimizes the generation of hazardous compounds during membrane preparation. The future trends and recommendations which could potentially be beneficial for researchers in this field are also highlighted.

Surface functionalization and modification including the grafting process are effective approaches to improve and enhance the reverse osmosis (RO) membrane performance. This work is aimed to synthesize grafted/crosslinked cellulose acetate (CA)/cellulose triacetate (CTA) blend RO membranes using N‐isopropylacrylamide (N‐IPAAm) as a monomer and N,N‐methylene bisacrylamide (MBAAm) as a crosslinker. The morphology of these membranes was analyzed by scanning electron microscopy and their surface roughness was characterized by atomic force microscopy. The performance of these membranes was evaluated through measuring two major parameters of salt rejection and water flux using RO unit at variable operating pressures. It was noted that the surface average roughness obviously decreased from 148 nm for the pure CA/CTA blend membrane with 2.5% CTA to 110 nm and 87 nm for the grafted N‐IPAAm and grafted/crosslinked N‐IPAAM/MBAAm/CA/CTA‐RO membranes, respectively. Moreover, the contact angle decreased from 51.98° to 47.6° and 43.8° after the grafting and crosslinking process. The salt rejection of the grafted CA/CTA‐RO membrane by 0.1% N‐IPAAm produced the highest value of 98.12% and the water flux was 3.29 L/m2h at 10 bar.
