“…Pure cellulose foam possesses a specific surface area of 13 m 2 /g due to the dominant macropores, while CM-1 shows a specific surface area of 177 m 2 /g. The pore size distribution of CM-1 indicated a hierarchical pore structure is formed, contributing to a higher value of BET specific surface area. , …”

In this Article, a hybrid foam was fabricated through the integration of amine-functionalized Fe-MOF (MIL-101-NH2) into cellulosic matrix. The existence of enormous group linkages and ionic bonding interactions among the composite foam network leads to a uniform dispersion of MIL-101-NH2 and high affinity between the MOF and cellulose skeleton. As-prepared hybrid foams were utilized as photocatalysts to reduce toxic hexavalent chromium ions (Cr(VI)) under visible light. Optimal performance was observed over CM-1 (with a MIL-101-NH2 and nanocellulose mass ratio of 1:1). When compared to pure MOF nanoparticle counterparts, the CM-1 foam presented preferable and more efficient Cr(VI) removal performance. The reasons could be attributed to the hierarchal pore structure and uniform MOF loading. Moreover, the flexible foams could be easily separated from the solution and preserved more than 80% removal efficiency of Cr(VI) after 10 runs. This work would shed light on how to construct high-efficiency photocatalysts for environmental governance from sustainable materials.

“…The pore size distribution of CM-1 indicated a hierarchical pore structure is formed, contributing to a higher value of BET specific surface area. 40,41 The microstructure and morphology were observed by SEM. MIL-101-NH 2 (Fe) nanoparticles were octahedral in shape with diameters of about 400 nm (Figure S3).…”

“…The nanocellulose hybrid containing polyhedral oligomeric silsesquioxane was also investigated to remove reactive dyes ( Xie et al, 2011b ). More recently, iron-based metal-organic framework@cellulose aerogels were obtained for CR dye adsorption by the in situ growing method ( Huang et al, 2021a ). It achieved an adsorption capacity of 280.3 mg g −1 .…”

In recent years, faced with the improvement of environmental quality problems, cellulose and cellulose-based (nano) composites have attracted great attention as adsorbents. In this review article, we first report the recent progress of modification and functionalization of cellulose adsorbents. In addition, the adsorbents produced by the modification and functionalization of carboxymehyl cellulose are also introduced. Moreover, the cellulose-based (nano) composites as adsorbents are reviewed in detail. Finally, the development prospect of cellulose and cellulose-based (nano) composites is studied in the field of the environment. In this review article, a critical comment is given based on our knowledge. It is believed that these biomass adsorbents will play an increasingly important role in the field of the environment.

“…There are two reasons for this morphology. First, CMC molecular chains entangle with lamellar ES-LDHs to form these layered structures [37][38][39]. Second, the composite aerogel is prepared by the classic freeze-casting and then freeze-drying method, the resulting pores are the routes left by the ice crystals [40,41].…”

Cobalt (Co) ion is a common heavy metal ion and the main metal ion in nuclear wastewater. However, the study on the absorption for Co(II) is not sufficient. Herein, a novel ES-layered double hydroxide (LDH) is prepared by intercalated ethylenediaminetetraacetic acid disodium salt (EDTA) and sodium dodecylbenzene sulfonate (SDBS) in a magnesium, iron pristine LDH, which is subsequently used for ES-LDH@carboxymethyl cellulose (CMC) composite aerogel. The results of Fourier transform infrared spectroscopy, X-ray diffraction spectra and thermogravimetric analysis shows successfully preparation of intercalated LDH. The pore morphology, specific surface area and pore size distribution of the composite aerogels are characterized by scanning electron microscope and Nitrogen-BET curves. The significantly improved adsorption capacity, adsorption kinetics and isotherms the absorbents on Co(II) are systematically revealed. This study thus provides an important understanding and path for dealing with the threat of Co(II).
