“…The phenomenon can be explained by the fact that cotton fibers are converted into CF containing amorphous carbon after high-temperature carbonization . In addition to the characteristic diffraction peak of type I cellulose at 22.9° (002), ZIF-67@CF also shows new diffraction peaks at 7.4, 10.4, 12.7, 14.8, 16.5, 18.0, 24.5, and 25.5°, corresponding to the (011), (002), (112), (002), (013), (222), (233), and (224) crystal planes of the ZIF-67 crystal, respectively, which indicates that ZIF-67 is successfully loaded on the cotton fiber (Figure a). The characteristic diffraction peaks belonging to ZIF-67 disappear after pyrolysis, and new derivative peaks appear at 44.2, 51.5, and 76.1°, corresponding to the (111), (200), and (220) crystal planes of cobalt metal, respectively .…”

Pregnant women are often faced with electromagnetic pollution, edema, joint pain, mobility difficulties, and abnormalities in the heart rate. Designing targeted multifunctional intelligent wearable devices to shield against electromagnetic radiation hazards, relieve edema and joint pain, monitor movement and pulse is urgent. Herein, an unprecedented strategy is proposed to combine a metal–organic framework and a fabric substrate for electromagnetic interference shielding. Co@C@carbon fabric (Co-CCF) derived from ZIF-67@cotton fabric was prepared by simple in situ growth and annealing. Subsequently, the Co-PCCF was prepared by encapsulating Co-CCF using polydimethylsiloxane, which improves corrosion resistance and adhesive strength. Co-PCCF-1000 (annealing at 1000 °C) with a double conductive network structure shows efficient electromagnetic shielding performance (blocks more than 99.9% of electromagnetic waves). Co-PCCF with flexibility also shows fantastic fastness and stability to avoid damages during their use by pregnant women (still blocks more than 99% of electromagnetic waves after being repeatedly bent for 500 cycles at 90° and undergoing the ultrasonic treatment for 1 h and 1 M acid/salt/alkali corrosion for 12 h, respectively). In addition, Co-PCCF can reach the required thermal therapy temperature by controlling the voltage (1.5–3 V corresponding to 41.8–84.9 °C) and illumination intensity (0.2 W/cm2 corresponding to 70.8 °C). Meanwhile, Co-PCCF can monitor a wide range of human movement in real time, such as pulse, breath, and joint activities. Multifunctional Co-PCCF designed for pregnant women can effectively prevent electromagnetic pollution, relieve joint pain, and detect the human movement and possesses wide application prospects.

The yolk-shell Co 3 O 4 @Fe 3 O 4 /C nanocomposites with Co 3 O 4 as the core, Fe 3 O 4 /C as the shell, and a cavity structure were synthesized by the hard template method. The physical and chemical properties of the composites were characterized by SEM, TEM, XRD, TGA, XPS, BET, and VSM. The specific surface area of yolk-shell Co 3 O 4 @Fe 3 O 4 /C nanocomposites is 175.9 m 2 g À 1 , showing superparamagnetic properties. The yolk-shell Co 3 O 4 @Fe 3 O 4 /C nanocomposites were used as heterogeneous Fenton catalysts to activate peroxymonosulfate (PMS) to degrade MB, which showed high catalytic degradation performance. The degradation rate of MB reached 100 % within 30 min under the circumstances of the yolk-shell Co 3 O 4 @Fe 3 O 4 /C nanocomposites dosage of 0.1 g L À 1 , the PMS dosage of 1.0 g L À 1 , the initial MB concentration of 100 mg L À 1 , an initial pH of 5.5, and a temperature of 30 � 2 °C. The enhanced catalytic performance of the yolk-shell Co 3 O 4 @Fe 3 O 4 /C nanocomposites can be attributed to the synergistic effect of the two catalytically active materials and the middle cavity. The effects of different operating parameters and co-existing anion species on MB degradation were also investigated. Electron paramagnetic resonance (EPR) analysis and quenching experiments confirmed that the formation of SO 4 *À in the yolk-shell Co 3 O 4 @Fe 3 O 4 /C/PMS system contributes to MB degradation. In addition, yolk-shell Co 3 O 4 @Fe 3 O 4 /C nanocomposites can be easily separated from the pollutant solution under the action of an external magnetic field, and the degradation rate of MB can still reach 98 % after five cycles, indicating that it has good stability and reusability and has broad application prospects in the field of water purification.

“…The membrane, containing Co catalytic centers, was able to catalytically activate peroxymonosulfate (PMS) to generate SO 4 − and OH, resulting in the rapid degradation of methylene blue dye and Rhodamine B dye into low-molecular weight substances, further degrading into CO 2 and H 2 O within 1 min. The hybrid membrane worked effectively in a wide pH range of 4-9, with good stability and reusability [44]. In another work, ZIF-9 or ZIF-12 were separately loaded on cellulose aerogel (as shown in Figure 11a,b) to activate PMS for the degradation of various pollutants, e.g., Rhodamine B, tetracycline hydrochloride, and p-nitrophenol (PNP).…”

Metal organic frameworks (MOFs) have gained remarkable interest in water treatment due to their fascinating characteristics, such as tunable functionality, large specific surface area, customizable pore size and porosity, and good chemical and thermal stability. However, MOF particles tend to easily agglomerate in nanoscale, thus decreasing their activity and processing convenience. It is necessary to shape MOF nanocrystals into maneuverable structures. The in situ growth or ex situ incorporation of MOFs into inexpensive and abundant cellulose-family materials can be effective strategies for the stabilization of these MOF species, and therefore can make available a range of enhanced properties that expand the industrial application possibilities of cellulose and MOFs. This paper provides a review of studies on recent advances in the application of multi-dimensional MOF–cellulose composites (e.g., aerogels, membranes, and bulk materials) in wastewater remediation (e.g., metals, dyes, drugs, antibiotics, pesticides, and oils) and water regeneration by adsorption, photo- or chemocatalysis, and membrane separation strategies. The advantages brought about by combining MOFs and cellulose are described, and the performance of MOF–cellulose is described and compared to its counterparts. The mechanisms of relative MOF–cellulose materials in processing aquatic pollutants are included. Existing challenges and perspectives for future research are proposed.
