“…The positions and the ratio of intensities of the two bands ID/IG were listed in Table 1. The intensity ratio of bands D and G (ID/IG) is important for describing carbon atoms' disordered structure, including lattice and edge defects caused by sp 3 -C formation due to the treatment process [35,44]. The increase of ID/IG indication creation of sp 3 -C, i.e., the addition of hetero O-atoms, affirms the successful treatment process.…”

“…This may be described as follows: the dye solution temperature increases and the motion of the dye species increases, the collision between the dye species and adsorption sites increases, and the adsorption efficiency increases. Additionally, this could be due to a temperature-induced enhancement in porosity and total pore volume of the adsorbents [44,56].…”

The main aim of this work is to treat sugarcane bagasse agricultural waste and prepare an efficient, promising, and eco-friendly adsorbent material. Biochar is an example of such a material, and it is an extremely versatile and eco-friendly biosorbent to treat wastewater. Crystal violet (CV)-dye and methylene blue (MB)-dye species are examples of serious organic pollutants. Herein, biochar was prepared firstly from sugarcane bagasse (SCB), and then a biochar biosorbent was synthesized through pyrolysis and surface activation with NaOH. SEM, TEM, FTIR, Raman, surface area, XRD, and EDX were used to characterize the investigated materials. The reuse of such waste materials is considered eco-friendly in nature. After that, the adsorption of MB and CV-species from synthetically prepared wastewater using treated biochar was investigated under various conditions. To demonstrate the study’s effectiveness, it was attempted to achieve optimum effectiveness at an optimum level by working with time, adsorbent dose, dye concentration, NaCl, pH, and temperature. The number of adsorbed dyes reduced as the dye concentrations increased and marginally decreased with NaCl but increased with the adsorbent dosage, pH, and temperature of the solution increased. Furthermore, it climbed for around 15 min before reaching equilibrium, indicating that all pores were almost full. Under the optimum condition, the removal perecentages of both MB and CV-dyes were ≥ 98%. The obtained equilibrium data was represented by Langmuir and Freundlich isotherm models. Additionally, the thermodynamic parameters were examined at various temperatures. The results illustrated that the Langmuir isotherm was utilized to explain the experimental adsorption processes with maximum adsorption capacities of MB and CV-dyes were 114.42 and 99.50 mgg−1, respectively. The kinetic data were estimated by pseudo-first and pseudo-second-order equations. The best correlation coefficients of the investigated adsorption processes were described by the pseudo-second-order kinetic model. Finally, the data obtained were compared with some works published during the last four years.

“…Pure carbonaceous materials can serve as the DLSC electrodes, provided that they are appropriately processed to develop a high specific surface area and exhibit high electric conductance. The specific surface area of different carbons varies widely and can attain values up to 3355 m 2 /g, when obtained from graphite, [69] or 3554 m 2 /g, when synthesized from sugarcane, [70] using a dry KOH activation process at 800 • C. The high surface area carbon materials can provide high electrochemical double-layer capacitance and can also serve as the supporting component and current collector in supercapacitors. The conductance and energy-storing capacity of these materials depend strongly on the structure and form of the material.…”

Supercapacitors are a new brand of high‐performance nanoengineered devices that match the high capacity of batteries for electric energy storage with the ability of dry capacitors for ultra‐fast charging or discharging rates. Thus, supercapacitors are capable of simultaneously providing the high energy‐density and high power‐density, demanded in a plethora of biosensors and portable electronic devices. In this review, a variety of nanomaterials investigated for possible applications in novel supercapacitors have been evaluated including different carbon nanoforms, metal oxides or hydroxides, chalcogenides, carbides and phosphates, as well as organic redox species, conductive polymers, metal‐organic frameworks, MXenes and others. Different strategies for boosting volumetric capacitance, power density and charge or discharge cycling stability of micro‐supercapacitors (MSCs) designed from these materials have been reviewed and their application potential assessed. Special attention has been given to micro‐supercapacitor's designs that are suitable for miniaturization and integration with flexible microcircuits for wearable and implantable biomedical devices, remotely rechargeable sensors, microprocessor‐controlled data processing chips, biomorphic computing, smart phone communication, military, automotive applications and emerging technologies. The different strategies applied for MSCs design and fabrication, including femto‐laser writing, photolithography, screen printing, stamping, inkjet printing, mask patterning and others, have been assessed. The exciting future perspectives of MSCs have been discussed.

“…Compared to many locally prepared activated carbons, the current activated carbon is superior in terms of the specific surface. For instance, the specific surface area of bentonite is 265 m 2 /g 26 , Parthenium hysterophorus-derived activated carbon is 268 m 2 /g 25 , Fe 3 O 4 -GO is 296 m 2 /g 24 and sugarcane bagasse is 2236.93 m 2 /g 58 . However, the surface area of the recently emerged adsorbent metal–organic framework is extremely high in the range of 1000–10,000 m 2 /g with good properties such as superior performances, tunability structure, thermal stability, and mechanically dispersible 59 – 61 .…”

Methylene blue (MB) is abundantly found in textile industrial effluent which can cause severe health problems for public and environmental ecology. Therefore, this study aimed to remove MB from textile wastewater using the activated carbon developed from Rumexabyssinicus. The adsorbent was activated using chemical and thermal methods, and then it was characterized by SEM, FTIR, BET, XRD, and pH zero-point charge (pHpzc). The adsorption isotherm and kinetics were also investigated. The experimental design was composed of four factors at three levels (pH (3, 6, and 9), initial MB concentration (100, 150, and 200 mg/L), adsorbent dosage (20, 40, and 60 mg/100 mL), and contact time (20, 40, and 60 min)). The adsorption interaction was evaluated using response surface methodology. The characterization of a Rumexabyssinicus activated carbon was found to have multiple functional groups (FTIR), an amorphous structure (XRD), crack with ups and down morphology (SEM), pHpzc of 5.03 and a high BET-specific surface area of 2522 m2/g. The optimization of MB dye removal was carried out using the Response Surface methodology coupled with the Box Behnken approach. The maximum removal efficiency of 99.9% was recorded at optimum conditions of pH 9, MB concentration of 100 mg/L, the adsorbent dosage of 60 mg/100 mL, and contact time of 60 min. Among the three adsorption isotherm models, the Freundlich isotherm model was the best fit with an experimental value at R2 0.99 showing the adsorption process was heterogeneous and multilayer whereas the kinetics study revealed that pseudo-second-order at R2 0.88. Finally, this adsorption process is quite promising to be used at an industrial level.
