“…Many researchers have investigated different carbon-based materials derived from renewable resources such as thiamine [16], tannin [17][18][19], used tea [20,21], coffee grounds [22][23][24], cornstalk [25,26], molasses [27,28], bamboo leaves [29], cotton [30] and many more for supercapacitor applications. Similarly, soy has also been demonstrated as being effective in charge storage applications by Huo et al [31] and Herde et al [32], yielding specific capacitance values as low as 4 F/g, and as high as 115 F/g. The soybean is a very prominent source of carbon, and is also one of Arkansas' most important crops, ranking 11th in the nation for soybean production as of 2019 statistics reported by the University of Arkansas [33].…”

Renewable resources and their byproducts are becoming of growing interest for alternative energy. Here, we have demonstrated the use of Arkansas’ most important crop, soy, as a carbon precursor for the synthesis of carbonized activated materials for supercapacitor applications. Different soy products (soymeal, defatted soymeal, soy flour and soy protein isolate) were converted into carbonized carbon and co-doped with phosphorus and nitrogen simultaneously, using a facile and time-effective microwave synthesis method. Ammonium polyphosphate was used as a doping agent which also absorbs microwave radiation. The surface morphology of the resulting carbonized materials was characterized in detail using scanning electron microscopy. X-ray photoelectron spectroscopy was also performed, which revealed the presence of a heteroelemental composition, along with different functional groups at the surface of the carbonized materials. Raman spectroscopy results depicted the presence of both a graphitic and defect carbon peak, with defect ratios of over one. The electrochemical performance of the materials was recorded using cyclic voltammetry in various electrolytes including acids, bases and salts. Among all the other materials, soymeal exhibited the highest specific capacitance value of 127 F/g in acidic electrolytes. These economic materials can be further tuned by changing the doping elements and their mole ratios to attain exceptional surface characteristics with improved specific capacitance values, in order to boost the economy of Arkansas, USA.

“…Previously, soy materials have been explored for supercapacitor applications. For example, pyrolyzed soybean hulls were used for the synthesis of KOH-activated carbons (AC) by Herde et al [32]. They performed electrochemical measurements in tetraethylammonium hexafluorophosphate, with propylene carbonate as the electrolyte.…”

“…Several parameters have a significant influence on the carbonization process [74] include the carbonization method, carbonization time, carbonization temperature, carbonization atmosphere, and chemical/physical modifications. The corn biochar preparation method and modification with different substances have significant influences on the specific surface area (SSA) [75] and the electrochemical performance of the corn biochar. [76][77][78] Corn pyrolysis in the molten salt, [79] microwave irradiation, [80] or the combination of some methods (hybrid carbonization).…”

The attention to renewable materials is amazingly increased in recent years to decrease environmental pollutions. Zea mays (corn) is one of the most produced plants by humans to provide food and energy. Hence, corn wastes as abundant and low-cost biomass are easily found throughout the world. Tremendous efforts have been accomplished in recent years to fabricate electrochemical energy storage devices (EES) from renewable biomass materials because of increasing attention to the environment. All main parts of EES devices include electrodes, binder, electrolyte, and membrane (separator) can be produced via corn waste biochar and corn derivatives. The low-cost corn-based EES devices not only decrease environmental pollution but also have significant electrochemical properties include specific capacitance and electrochemical durability. This review investigates state-of-the-art development in the corn-based EES devices.

“…Amongst those precursors, lignocellulosic biomasses emerge as promising green precursors in AC preparation for being renewable, vastly available, ecologically suitable, and costly effective (Supong et al 2019). In recent years, many studies have focused on utilizing various biomasses to be the alternative precursors for preparation of AC such as corn fiber and soy hulls (Herde et al 2020), tea waste (Inal & Aktas 2020), switchgrass (Yumak et al 2020), peanut shell (Wang et al 2020), cotton waste (Sartova et al 2019), pine pollen (Wan et al 2019), and bamboo chip (Jawad & Abdulhameed 2020). The use of raw materials from agricultural and industrial waste has also recovered its economic value, as most waste is normally ignored and disposed of (Bahrudin et al 2020).…”

In this work, sugarcane bagasse waste (SBW) was used as a lignocellulosic precursor to develop a high surface area activated carbon (AC) by thermal treatment of the SBW impregnated with KOH. This sugarcane bagasse waste activated carbon (SBWAC) was characterized by means of crystallinity, porosity, surface morphology and functional groups availability. The SBWAC exhibited Type I isotherm which corresponds to microporosity with high specific surface area of 709.3 m2/g and 6.6 nm of mean pore diameter. Further application of SBWAC as an adsorbent for methylene blue (MB) dye removal demonstrated that the adsorption process closely followed the pseudo-second order kinetic and Freundlich isotherm models. On the other hand, thermodynamic study revealed the endothermic nature and spontaneity of MB dye adsorption on SBWAC with high acquired adsorption capacity (136.5 mg/g). The MB dye adsorption onto SBWAC possibly involved electrostatic interaction, H-bonding and π-π interaction. This work demonstrates SBW as a potential lignocellulosic precursor to produce high surface area AC that can potentially remove more cationic dyes from the aqueous environment.
