“…After calculation, specific surface area of CAH is 149.90m 2 /g, the pore volume is 0.41cm 3 /g, and the pore size distribution is about 12.16nm, so CAH is a malodorous material. Compared with HA, the specific surface area of CAH is significantly increased, which is also consistent with the results of the SEM scan [43], [44] . Fig.…”

In this study, a carbon composite based on humic acid (CAH) was synthesized by partially carbonizing humic acid by using aluminum sulfate with a mass ratio of 2:3 and a leavening agent oxalic acid with a fixed mass. The morphology and microstructure of the sample are measured by scanning electron microscope (SEM), x-ray diffractometer (XRD), thermal analysis (TG-DSC), Raman spectroscopy (Raman), X-ray photoelectron spectroscopy (XPS) and Fourier Transform infrared spectroscopy (FT-IR) is used to analyze the composition and structure of materials. The BET surface area of CAH is determined to be 149 m²/g. Congo red was used as a model adsorbent for adsorption research. When the dye concentration is 400 mg/L and 10mg of adsorbent powder is used. CAH has the highest dye removal rate of adsorption capacity. The pseudo-first-order and pseudo-second-order kinetic models were used to describe the kinetic data and the Langmuir and Freundlich models were applied to describe the adsorption isotherms. The results showed that the equilibrium adsorption data were found to fit better to the Langmuir adsorption model and the kinetic process of adsorption could be described by the pseudo-second-order model. Compared with humic acid, CAH composite materials can effectively improve the adsorption rate and adsorption capacity of Congo red, and the adsorption capacity is as high as 3986mg/g within 30 minutes. In addition, considering the cost issue, this study selected low-cost humic acid as a carbon source to prepare composite materials, emphasizing the importance of cost.

“…The physical activation method is performed by inert‐atmosphere calcination, followed by high‐temperature (600–1200°C) activation with the introduction of suitable gasifying agents (CO 2 , 135,152–157 NH 3 , 158,159 Cl 2 , 160–163 and steam 164 ). In contrast, chemical activation includes mixing of carbonaceous materials and activating agents (e.g., KOH, 29,84,165–199 NaOH, 200 K 2 CO 3 , 201,202 H 3 PO 4 , 203–205 etc. ), followed by calcination at a lower temperature (400–900°C).…”

“…After removing the intercalated metallic potassium and other potassium compounds by washing/etching, HPCs with enhanced porosity and SSA were created due to the expanded carbon lattices. An example of a KOH‐activated silk cocoon‐derived porous HPC is shown in Figure 7A, 194 which could be simply obtained by precarbonization of silk cocoon, followed by KOH activation. With an increase in the weight ratio of KOH/carbon from 0.5 to 1.5, carbon could react more with KOH, leading to a much higher SSA of HPC‐1.5 (HPC‐X, X represents the weight ratios) than that of HPC‐0.5.…”

Lithium-sulfur (Li-S) batteries, although a promising candidate of nextgeneration energy storage devices, are hindered by some bottlenecks in their roadmap toward commercialization. The key challenges include solving the issues such as low utilization of active materials, poor cyclic stability, poor rate performance, and unsatisfactory Coulombic efficiency due to the inherent poor electrical and ionic conductivity of sulfur and its discharged products (e.g., Li 2 S 2 and Li 2 S), dissolution and migration of polysulfide ions in the electrolyte, unstable solid electrolyte interphase and dendritic growth on anodes, and volume change in both cathodes and anodes. Owing to the high specific surface area, pore volume, low density, good chemical stability, and particularly multimodal pore sizes, hierarchical porous carbon (HPC) materials have received considerable attention for circumventing the above problems in Li-S batteries. Herein, recent progress made in the synthetic methods and deployment of HPC materials for various components including sulfur cathodes, separators and interlayers, and lithium anodes in Li-S batteries is presented and summarized. More importantly, the correlation between the structures (pore volume, specific surface area, degree of pores, and heteroatom-doping) of HPC and the electrochemical performances of Li-S batteries is elaborated. Finally, a discussion on the challenges and future perspectives associated with HPCs for Li-S batteries is provided.

Lithium‐sulfur (Li−S) batteries are lighter and cheaper than today's electrochemical energy storage devices for the forthcoming generations. Particularly the low price and abundance of sulfur as the cathode material, high energy density, and theoretical capacity are delightful characteristics. However, Li−S batteries have many hindrances to attain their commercial applications. Among the challenges are the polysulfide shuttle effect, the insulating property of sulfur, and large volume expansion during charging‐discharging processes. Researchers have carried out comprehensive research on the potential solutions to these challenges. Environmental waste‐derived carbon has an increasingly important role in the energy storage devices (Li−S batteries) due to their sustainable development, low cost, heteroatom doping, large specific surface area, adjustable pore size, easily available sources, and high electric conductivity, which had a significant effect to enhance electrochemical performance. This review highlighted the research progress on carbon derived from environmental solid wastes for the application of Li−S batteries. Furthermore, the preparation, morphology, and design protocols of carbon derived from solid wastes are elaborated for energy storage devices focused on Li−S batteries. These properties inspire researchers in the rational design of environmental waste‐derived carbon materials for sustainable and advanced electrochemical energy storage devices.
