Because of its ability to store energy, the AC is also used in electrochemistry, e.g., for the construction of capacitors and batteries (Betzy and Soney 2015;Kolonowski et al 2020).…”

With the depletion of fossil fuel feedstocks, the lignocellulosic biomass, including the agro-wastes, can serve as the best alternative source to produce activated carbons (ACs). Corn biomass (corn leaves, stalks, cobs without kernels, silk, and kernels) were used to produce ACs in a two-step process. Crushed plant material was carbonized at 600 °C and then the obtained carbon was activated using potassium hydroxide at 750 °C. The content and type of surface oxygen functional groups were determined by the Boehm method and infrared spectroscopy. The porous structure of the obtained AC was determined by the nitrogen adsorption/desorption method at -196 °C, and the thermal resistance by the thermogravimetric method. The iodine number was also determined. The ACs derived from corn biomass were characterized with surfaces rich in chemical groups and revealed a highly developed porous structure. The specific BET surface area ranged from 1600 m2/g to 1965 m2/g. High values of iodine number approx. 1300 mg/g, indicated an extensive system of pores and their good adsorption properties.

“…The continuation of trends regarding porosity as a key property of the desired adsorption material, coupled with the need to use more sustainable and widespread materials, has led to an extensive investigation of different types of carbon materials. In recent decades, research on carbon materials in terms of their use as a potential adsorbent of various impurities has included activated carbons (ACs) [ 7 , 8 ], metal–carbon composites [ 9 , 10 ], bio-waste-derived carbons [ 11 , 12 ], and nitrogen-doped carbons [ 13 , 14 ]. The increased interest in describing activated carbon materials is most importantly associated with their physical properties, such as a large porous volume, well-defined pore size distribution, and as a result, a high specific surface area.…”

The adsorption properties of microporous spherical carbon materials obtained from the resorcinol-formaldehyde resin, treated in a solvothermal reactor heated with microwaves and then subjected to carbonization, are presented. The potassium-based activation of carbon spheres was carried out in two ways: solution-based and solid-based methods. The effect of various factors, such as chemical agent selection, chemical activating agent content, and the temperature or time of activation, was investigated. The influence of microwave treatment on the adsorption properties was also investigated and described. The adsorption performance of carbon spheres was evaluated in detail by examining CO2 adsorption from the gas phase.

Summary Renewable carbon materials are attractive materials with great potential for many applications. Macadamia nutshell is a by‐product of the nut industry, with high yield and fast regeneration. It is a potential precursor for biomass‐based activated carbon. In this study, we prepared an adsorbent using macadamia nutshell as a precursor and KOH as an activator. To prepare the samples with the highest CO2 uptake, the preparation process was optimized by response surface methodology (RSM). Interactions between different activation conditions were investigated, and their effects on CO2 uptake were explored. Meanwhile, visual three‐dimensional images were used to describe the effects of activation conditions and interactions on adsorption capacity. It was found that the activation conditions affected the location of the central region (high CO2 uptake region) of the carbon material. Meanwhile, the interaction between different activation conditions has a significant influence on the growth of pores during the activation process. The preparation conditions optimized by RSM in this study are as follows: activation temperature is 771°C, KOH/C is 1.7, and time is 2.3 h. At 0°C and 1 bar, the carbon sorbent prepared under optimized conditions has a CO2 adsorption capacity of 6.58 mmol/g. This study confirms that RSM is an effective method to optimize the preparation process of high‐efficiency carbon adsorbents for CO2 uptake.
