“…Benefiting from the porous structure and high specific surface area (1593 m 2 g −1 ), an excellent adsorption capacity of methylene blue (MB) dye of 415 mg g −1 was delivered (Table 2). In addition, Liu et al [99] prepared hydrophilic porous carbon nanosheets with very high specific surface area using lotus leaves (LL) as the carbon source, and they found that sp 3 hybrid carbon could be converted to sp 2 hybrid carbon through carbonization. Carbonized at 500 °C, the amount of sp 2 hybrid carbon and oxygen was optimized.…”

With the development of economy and increasing environmental awareness, how to effectively remove organic pollutants in wastewater is a research hotspot. Adsorption is one of the effective methods, and the adsorption material is the key factor to determine the efficiency. In this review, biomass‐derived carbon materials as adsorbents of organic pollutants and the adsorption mechanism are discussed in depth. The effects of carbonization and activation on the morphology and structure of carbon materials; the modification strategies of carbon adsorbents, the adsorption performance of biomass‐derived carbon materials for organic pollutants are described and illustrated; the future work of the biomass‐derived carbon materials is proposed.

The exploration of low-cost, high-performance adsorbents is a popular research issue. In this work, a straightforward method that combined hydrothermal with tube firing was used to produce Osmanthus fragrans biomass charcoal (OBC) from low-cost osmanthus for dye adsorption in water. The study examined the parameters of starting concentration, pH, and duration, which impacted the process of adsorption of different dyes by OBC. The analysis showed that the adsorption capacities of OBC for six dyes: malachite green (MG, C0 = 800 mg/L, pH = 7), Congo red (CR, C0 = 1000 mg/L, pH = 8), rhodamine B (RhB, C0 = 500 mg/L, pH = 6), methyl orange (MO, C0 = 1000 mg/L, pH = 7), methylene blue (MB, C0 = 700 mg/L, pH = 8), and crystalline violet (CV, C0 = 500 mg/L, pH = 7) were 6501.09, 2870.30, 554.93, 6277.72, 626.50, and 3539.34 mg/g, respectively. The pseudo-second-order model and the Langmuir isotherm model were compatible with the experimental findings, which suggested the dominance of ion exchange and chemisorption. The materials were characterized by using XRD, SEM, FTIR, BET, and XPS, and the results showed that OBC had an outstanding specific surface area (2063 m2·g–1), with potential adsorption mechanisms that included electrostatic mechanisms, hydrogen bonding, and π-π adsorption. The fact that the adsorption capacity did not drastically decrease after five cycles of adsorption and desorption suggests that OBC has the potential to be a dye adsorbent.
