“…Nanoporous carbon materials (NCMs) have received considerable attention for their potential properties of adsorption of pollutants from an aqueous phase [1][2][3][4][5]. Industrial pollutants from textile and carpet dyeing industries possess intense color, so that the effluents from carpet dyeing industries not only change water color which is important for aesthetics, but also prevent light from penetrating through water, destroying the aquatic ecosystem and several aquatic species.…”

Abstract:In this paper, wool carpet dye adsorption properties of nanoporous activated carbon materials (NCMs) prepared from bamboo agro-product is reported. Bamboo cane powder was chemically activated with phosphoric acid at different temperatures (400, 500, and 600 • C) at an impregnation ratio of 1:1. We found that the specific surface area and the total pore volume of NCM increases with temperature giving the highest surface area and pore volume ca. 2130 m 2 ·g −1 and 2.69 cc·g −1 at 600 • C. Owing to superior surface textural properties, bamboo-derived NCM showed excellent adsorption capacity for wool carpet dyes Lanasyn orange (LO) and Lanasyn gray (LG). The adsorption phenomena could be described by Langmuir/Freundlich adsorption isotherm models. The maximum adsorption capacity was ca. 2.60 × 10 3 and 3.04 × 10 3 mg·g −1 for LO and LG, respectively. The adsorption followed pseudo second order kinetics with the second order rate constant of 1.24 × 10 −3 g·mg −1 ·min −1 (LO) and 7.69 × 10 −4 g·mg −1 ·min −1 (LG), respectively. This study demonstrated that the high surface area NCMs prepared from agro-product can be used as efficient and cost-effective adsorbent materials for the removal of dyes from industrial effluent.

Sulfate radical (SO 4 c À ) based advanced oxidation processes allow efficient degradation of refractory organics, but efficient, low-cost, and robust catalysts for such processes are still lacking. In this work, a magnetically recoverable heterogeneous catalyst was fabricated by immobilizing spinel cobalt-ferrite (CoFe 2 O 4 ) particles on graphitic carbon nitride nanosheets (CNS) using a low-cost, one-step solvothermal method. In the CoFe 2 O 4 -CNS nanocomposite, the CoFe 2 O 4 particles were evenlydistributed on the CNS surface, giving the nanocomposite a high specific surface area and significantly raised activity for peroxymonosulfate (PMS) activation and sulfonamide degradation compared to the bare CoFe 2 O 4 NPs, which were considerably aggregated. In addition, the CoFe 2 O 4 -CNS could be more efficiently separated under magnetic field and resuspended compared with the bare CoFe 2 O 4 due its larger sizes and no agglomeration. A stable activity of the nanocomposite catalyst during repeated use was also demonstrated. Our results imply high potential of CoFe 2 O 4 -CNS for sustainable water treatment and environmental remediation applications.

“…The peak at 3100–3300 cm −1 belongs to‐NH 2 or ‐NH‐ peaks. It is ascribed to the defect area of the aromatic ring . Comparing to the pure g‐C 3 N 4 , a stronger adsorption at 3442 cm −1 is observed for the CS sample, which originated from the stretching vibrations of O−H or ‐COOH.…”

In this work, the preparation, characterization and removal capability of hierarchically porous carbonaceous sponges and their g-C 3 N 4 /CS composites were described. Possessing a hierarchically porous structure and extremely large surface areas, g-C 3 N 4 /CS composites are demonstrated to have advantages in adsorption and photocatalytic activities. The adsorption and photocatalytic activities of the as-prepared catalysts were evaluated by the degradation of RhB, MO, and phenol. The best results showed that 97% decomposition of RhB was obtained by using g-C 3 N 4 /CS-60 composites within 20 min at 25°C under visible light irradiation. Furthermore, the g-C 3 N 4 / CS-60 composites showed remarkable regeneration stability, which maintains high photocatalytic activity after the samples are saturated. Additionally, the degradation mechanisms of RhB and the photocatalytic mechanism are explained in this paper.
