“…The presented protocol mainly differs from state‐of‐the‐art preparation methods in the pretreatment step. In the case of cellulose‐derived composites, the pretreatment involves TEMPO (2,2,6,6‐tetramethylpiperidine‐1‐oxyl radical)‐ mediated oxidation, esterification, cysteamine, or carboxymethylation reactions, which are performed in the presence of toxic chemicals such as sodium hypochlorite (NaClO), cyanuric chloride (C 3 Cl 3 N 3 ), and sodium chloroacetate (ClCH 2 COONa) . In contrast, the treatment with NaOH offers a simple and renewable solution for the targeted wood functionalization.…”

The applicability of advanced composite materials with hierarchical structure that conjugate metal–organic frameworks (MOFs) with macroporous materials is commonly limited by their inferior mechanical properties. Here, a universal green synthesis method for the in situ growth of MOF nanocrystals within wood substrates is introduced. Nucleation sites for different types of MOFs are readily created by a sodium hydroxide treatment, which is demonstrated to be broadly applicable to different wood species. The resulting MOF/wood composite exhibits hierarchical porosity with 130 times larger specific surface area compared to native wood. Assessment of the CO2 adsorption capacity demonstrates the efficient utilization of the MOF loading along with similar adsorption ability to that of pure MOF. Compression and tensile tests reveal superior mechanical properties, which surpass those obtained for polymer substrates. The functionalization strategy offers a stable, sustainable, and scalable platform for the fabrication of multifunctional MOF/wood‐derived composites with potential applications in environmental‐ and energy‐related fields.

“…Metal–organic frameworks (MOFs) are porous structures which allows a good interaction of water pollutants with the MOF metal centers [1] . The deposition MOFs on cellulose has the advantage of providing a substrate as well as improving the diffusion and enhancing the interaction of the MOFs with aqueous media [2–6] . Cellulose can be covalently modified with carboxyl groups [7, 8] that mimic carboxyl groups present in the MOF's ligands, hence increasing the chemical interaction between a MOF structure and cellulose [5] …”

The development of portable, reliable, and low‐cost sensors for assessing the quality of natural water sources is of high relevance in developing countries as they can serve as an intermediate solution prior to the building of permanent potable water distribution infrastructure. These sensors should be simple to operate by non‐trained operators and easy to manufacture locally. Lanthanide‐based metal–organic frameworks (MOFs) offer a trustable platform due to their intense emission in regions of the visible spectra and their high sensitivity to fluorides in water. Cotton was chosen as a substrate due to its high hydrophilicity which, together with the highly porous nature of the MOF, allows for shorter reaction times. The modified cotton was characterized by XRD, SEM as well as XAFS, hence probing the presence of [Tb(BTC)6(H2O)] (Tb‐BTC) attachment to cotton. Changes in the emission when Tb‐BTC modified cotton was exposed to water and aqueous fluoride solutions were monitored as a function of time. Crystalline phase changes were identified that correlated to structural information. Finally, the Tb‐BTC modified cotton was used to build a fluoride demonstrator sensor with a linear response of up to 10 mg L−1 and a limit of detection of 0.8 mg L−1, making it suitable for drinking water analysis under international regulations.

“…In addition to PDA and TA coating, the interfacial synthesis of metal–organic frameworks (MOFs) on nanocelluloses can be conducted in aqueous conditions. [ 66–68 ] Recently, Zhou et al. coated conductive MOF layers on TOCNs to form TOCN@MOFs, in which TOCNs served as substrates for MOF growth (Figure 4c).…”

How do trees support their upright massive bodies? The support comes from the incredibly strong and stiff, and highly crystalline nanoscale fibrils of extended cellulose chains, called cellulose nanofibers. Cellulose nanofibers and their crystalline parts—cellulose nanocrystals, collectively nanocelluloses, are therefore the recent hot materials to incorporate in man‐made sustainable, environmentally sound, and mechanically strong materials. Nanocelluloses are generally obtained through a top‐down process, during or after which the original surface chemistry and interface interactions can be dramatically changed. Therefore, surface and interface engineering are extremely important when nanocellulosic materials with a bottom‐up process are fabricated. Herein, the main focus is on promising chemical modification and nonmodification approaches, aiming to prospect this hot topic from novel aspects, including nanocellulose‐, chemistry‐, and process‐oriented surface and interface engineering for advanced nanocellulosic materials. The reinforcement of nanocelluloses in some functional materials, such as structural materials, films, filaments, aerogels, and foams, is discussed, relating to tailored surface and/or interface engineering. Although some of the nanocellulosic products have already reached the industrial arena, it is hoped that more and more nanocellulose‐based products will become available in everyday life in the next few years.
