Advances in nanoscale science and engineering are providing new opportunities to develop promising adsorbents for environmental remediation. Here, hybrid aerogels are assembled from cellulose nanofibrils (CNFs) and carbon nanomaterials to remove cationic dye methylene blue (MB) and anionic dye Congo red (CR) in single and binary systems. Two classes of carbon nanomaterials, carbon nanotubes (CNTs) and graphene nanoplates (GnPs), are incorporated into CNFs with various amounts, respectively. The adsorption, mechanics and structure properties of the hybrid aerogels are investigated and compared among different combinations. The results demonstrate CNF–GnP 3:1 hybrid exhibits the best performance among all composites. Regarding a single dye system, both dye adsorptions follow a pseudo-second-order adsorption kinetic and monolayer Langmuir adsorption isotherm. The maximal adsorption capacities of CNF–GnP aerogels for MB and CR are 1178.5 mg g−1 and 585.3 mg g−1, respectively. CNF–GnP hybrid show a superior binary dye adsorption capacity than pristine CNF or GnP. Furthermore, nearly 80% of MB or CR can be desorbed from CNF–GNP using ethanol as the desorption agent, indicating the reusability of this hybrid material. Hence, the CNF–GnP aerogels show great promise as adsorption materials for wastewater treatment.

“…Particularly for CR,t he maximum absorption of Fc-HPP is significantly higher than that of other porous polymers ( Table S4 in the Supporting Information). [15,31,42] To further understand the absorption process of Fc-HPP, we also investigated the absorption kinetics by taking CR as an example with af ixed initial concentration of 30 mg L À1 .U pon addition of the Fc-HPPp owder,d ye absorption was monitored by UV/Vis absorption spectroscopy of the aqueous solution at differentt ime intervals. It was observed that absorption reachedaconstantvery fast, after about 60 min, as determined from the decrease of the absorption intensity at 497 nm (Figure 8a nd Figure S4 in the Supporting Information), manifesting CR was rapidly absorbed by Fc-HPP.F urthermore, the color of the solution turned from dark red to paler ed, then to nearly colorless, while the Fc-HPP power becamer ufescent (as shown in the inset of Figure 8).…”

A novel ferrocene-linked organic-inorganic hybrid porous polymer has been successfully prepared by Friedel-Crafts reaction of octavinylsilsesquioxane and ferrocene. The relationship of structure/property was investigated by FTIR, NMR, XRD, Brunauer-Emmett-Teller (BET) etc. The obtained porous polymer exhibited a high surface area of 1015 m g and a hierarchical pore structure. It could be applied to wastewater treatment with the absorption capacity of up to 1683 mg g for Congo red (CR), 1083 mg g for crystal violet (CV), 1003 mg g for rhodamine B (RB), 441 mg g for methylene blue (MB), 191 mg g for Hg , and 328 mg g for Pb . Remarkably, it could be easily regenerated and the removal efficiency remains almost constant even after six cycles.

“…Taking the similar chemical characteristics into consideration, and inspired from previous work, porous Ni/C composites were gained from Ni‐based MOFs, and exhibited a good RL value of 51.80 dB . Likely using Ni‐containing MOF, Jin et al prepared porous carbon/carbon nanotube hybrids encapsulating nickel nanoparticles (Ni/PC‐CNT). On account of the high surface area (999 m 2 g −1 ), large pore volume (0.90 cm 3 g −1 ) and well‐developed graphitized wall, the Ni/PC‐CNT composites showed excellent adsorption capacities of ≈898 mg g −1 for malachite green (MG), 818 mg g −1 for Congo red (CR), 395 mg g −1 for rhodamine B (Rh B), 312 mg g −1 for methylene blue (MB), and 271 mg g −1 for methyl orange (MO) dyes.…”

production, especially for hydroelectricity, sunlight, and wind energy, which cannot be gathered or released when they are needed. [5][6][7][8] Electrochemical energy storage devices provide a promising approach for the storage of electric energy from these sources. [9][10][11] Currently, carbonaceous materials have attracted much interest for their extensive applications including adsorption, [12] catalysis, [13] batteries, [14] fuel cells, [15,16] supercapacitors, [17,18] and drug delivery and imaging. [19] In addition, some sensors are also one of the important applications of carbonaceous materials, because they are closely related to human health. [20,21] For instance, Emran and co-workers [22] constructed ultrasensitive biosensors with N-doped mesoporous carbon (NMC)-based electrodes for in vitro monitoring of DA released from living cells. With the further study of the experiment, they also designed a series of S-doped carbon materials for a wider detection of DA, UA (uric acid), and AA (ascorbic acid). [23,24] The advantages of easy preparing, nontoxic and excellent electrical conductivity of carbonaceous materials, which are rare among energy storage materials, make carbonaceous materials superior to most of the energy storage materials. [25][26][27] There are varieties of approaches for the preparation of carbon materials, such as directly carbonizing from organic precursors, physically or chemically carbonizing from carbon, template methods using zeolites and mesoporous silica, solvothermal and hydrothermal methods with elevated temperature, the electrical arc methods, and chemical vapor decomposition (CVD) methods. [28][29][30][31][32][33][34] Among all these approaches, directly carbonizing from organic precursors is the most frequently used method to prepare nanoporous carbons (NPCs) due to its flexibility and simplicity. [35][36][37] However, these NPC materials present certain drawbacks, such as low surface areas, disordered structures, and ununiformed sizes, which will greatly limit their applications. [25] As studies have progressed, researchers found that carbon materials derived from metalorganic frameworks (MOFs) could overcome these limitations.Metal-organic frameworks, which are also named porous coordination polymers (PCPs), are crystalline porous materials with periodic network structures formed by metal ions (or metal clusters) and organic ligands. [38][39][40][41][42] They are usually prepared by solvothermal methods and used as precursors or templates to form nanostructured materials. [43][44][45] So far, many researchers have highlighted the advantages of MOFs. For Carbon materials derived from metal-organic frameworks (MOFs) have attracted much attention in the field of scientific research in recent years because of their advantages of excellent electron conductivity, high porosity, and diverse applications. Tremendous efforts are devoted to improving their chemical and physical properties, including optimizing the morphology and structure of the carbon materials, compositing them wi...
