A novel carbon monolith material with embedded mesopores and nanoparticles has been synthesized via a facile catalytic graphitization process by using natural wood as the carbon precursor. BET results reveal a large specific surface area of 273.0 m 2 g À1 and a narrow pore size distribution, with pore diameters of $4.0 nm. This unique material shows excellent toxic pollutants removal from water, including inorganic heavy metal ion (chromium(VI)) and organic dyes (methylene blue and methyl orange). Isothermal studies reveal its large removal capacities of 49.5, 61.7 and 68.2 mg g À1 for chromium(VI), methyl orange and methylene blue, respectively. Kinetic studies reveal that the removal process follows pseudo-secondorder adsorption behavior. A mechanism study demonstrates that adsorption, electrostatic interaction and a redox reaction are involved in the pollutant removal process, and contribute to the large adsorption capacities and excellent rate performance. The widely accessible natural resources, low cost, convenient fabrication, and superior adsorption properties would facilitate this new material promising applications in the fields of water pollutant control and purification.

“…As a waste product from paper industry, LS is also an amphiphilic biopolymer, which has been widely used as a surfactant, effective adsorbent to remove heavy metal from industrial wastewater, and supporting material for noble metal for catalysis, etc. [24][25][26] The sulfonic group of LS is usually introduced into the a-position of the phenylpropane structure of lignin by cleavage of the side chain, and can be obtained from LS by a simple proton-exchanged process (Fig. 1).…”

The application of biopolymer based catalyst in catalysis is attracting more and more attention in the field of chemistry. Lignosulfonic acid (LSA), which is an organic waste generated as a byproduct from pulp and papermaking industry, could be serves as a retrievable sustainable heterogeneous catalyst for multicomponent reactions under solvent-free condition, such as one-pot synthesis of benzoxanthenes by condensation reaction of dimedone with aldehyde and 2-naphthol, etc in excellent yields. Furthermore, the as synthesized solid acid catalyst could be used for several cycles without significant loss of catalytic activity. These results clearly show that the lignin-derived catalyst is economic, eco-friendly, and promising for green chemical reaction from low-cost feedstocks and may find wide applications.

“…Yang et al [70] employed a new adsorbent, lignosulfonate-GO-polyaniline (LS-GO-PANI) ternary nanocomposite, to adsorb Pb(II) from water. GO was first fabricated from expansible graphite via an airtight oxidation method, and then LS-GO-PANI was prepared through an in situ polymerization of aniline in the presence of LS and GO in a HCl aqueous solution, as shown in Fig.…”

Carbon nanoadsorbents have attracted tremendous interest for metal ion removal from wastewater due to their extraordinary aspect ratios, surface areas, porosities, and reactivities. However, challenges still exist as they suffer from subpar dispersion and recovery, tending to aggregate, and so on. Thus, significant research efforts focus on modification of these carbon nanomaterials to increase the dispersions and recoveries, while maintaining or even enhancing the desirable properties. This review aims to give an in-depth look at recent and impactful advances in metal ion adsorption applications involving these modified carbon nanostructures. Here, the advanced design and testing of modified carbon nanostructures for metal ion removal are emphasized with comprehensive examples, and various adsorption behaviors and mechanisms are discussed, which are hoped to help the development of more effective adsorbents for water treatment.
