“…The char yield increased from 1.5 wt % for neat FPUF to 12.37 wt % for FPUF@Si/MO, indicating that the MOF composites obviously enhanced the thermal resistance of FPUF composites. According to a previous publication, the catalytic carbonization effect of CuO helped to enhance the formation of char residues during FPUF degradation, which is consistent with the experimental results in this work.…”

In order to separate heavy-metal ions from contaminated wastewater and further realize the reutilization of waste adsorbent, magnetic composites with flowerlike structure were successfully synthesized. After the absorption of Cu 2+ ions, hybrids can be used as effective coatings to enhance the fire safety of flexible polyurethane foam (FPUF) through a dip-coating method. As-fabricated metal−organic framework (MOF)-based composites exhibited a core−shell and flowerlike structure with high thermal stability. The maximum adsorption capacity for Cu 2+ could reach 292.13 mg•g −1 , calculated from the Langmuir isotherm model. In order to reutilize the adsorbed Cu 2+ ions, the CuOloaded MOF-derived Fe 3 O 4 @ZnO@CuO (MO) was obtained with a simple heat treatment. The effectivity of MO as a fire-safety coating for inhibiting the release of heat and toxic gases of FPUF was satisfactory. The application of this MOF-based composite will provide useful insights into the design of bifunctional materials for efficient wastewater remediation and fire-safety coatings.

“…These results suggest that Cu 2+ coordinates with the N and O atoms after adsorption. Additionally, the Cu 2p spectra exhibit multiple peaks, including Cu 2+ 2p3/2 (933.8 eV), Cu 2+ 2p1/2 (953.6 eV), Cu + 2p3/2 (935.6 eV), Cu + 2p1/2 (955.3 eV), and Cu 2+ satellite (943.1 and 962.9 eV) (Figure c). − These findings indicate that redox reactions occurred at the interface of the CuCl 2 electrolyte and the electrodes. XRD characterized the samples after Cu 2+ was adsorbed, as shown in Figure d; we can find CuO, Cu 2 Om, and CuCl 2 patterns in the spectra; the results are consistent with the XPS results mentioned above.…”

Dried bamboo shoots (DBS) are a natural resource with inherent silica content, which can serve as sacrificial templates for the formation of mesoporous carbon but also promote the generation of silicon carbide (SiC). Building on this, we introduced mesoporous and graphitic carbon/SiC (SiC/BSC) as the CDI electrode for copper ion (Cu 2+ ) removal. Mesoporous carbon electrodes facilitate faster ion transport, diffusion, and electron-transfer pathways. Furthermore, SiC accelerates electron transfer and promotes faradic redox reactions during the charge and discharge processes. Consequently, the synergistic effect of SiC/ BSC mesoporous carbon material leads to a promising electrode for Cu 2+ capacitive deionization. Leveraging these unique properties, the SiC/BSC electrode material exhibits an outstanding CDI performance of 381.5 mg/g at 1.8 V. This study offers a strategy for the preparation of efficient mesoporous carbon materials as CDI electrodes, specifically tailored for the deionization of Cu 2+ ions.

“…The capture of these heavy metals is of crucial importance for a healthy environment. Hu et al employed an interesting strategy to coat COFs with polydopamine (PDA) [109]. The COF@PDA showed an excellent adsorption affinity towards Cu(II) and the adsorption equilibrium was achieved within ten minutes with an adsorption capacity of 109.2 mg/g.…”

Covalent organic frameworks (COFs) are emerging crystalline polymeric materials with highly ordered intrinsic and uniform pores. Their synthesis involves reticular chemistry, which offers the freedom of choosing building precursors from a large bank with distinct geometries and functionalities. The pore sizes of COFs, as well as their geometry and functionalities, can be pre-designed, giving them an immense opportunity in various fields. In this mini-review, we will focus on the use of COFs in the removal of environmentally hazardous metal ions and chemicals through adsorption and separation. The review will introduce basic aspects of COFs and their advantages over other purification materials. Various fabrication strategies of COFs will be introduced in relation to the separation field. Finally, the challenges of COFs and their future perspectives in this field will be briefly outlined.
