“…The atmosphere for carbonization and activation is crucial in KOH‐activated carbon preparation. Nitrogen atmosphere is mostly reported 4, 7, 11, 12, 28, 49, 57, 69, 70, 173–175, 177, 183, 185–187, 190–197 and some researchers did not state the atmospheric condition under which their KOH‐activated carbons were prepared, e.g., Donnaperna et al. 19 Guizhen et al.…”

This review covers research on the use of potassium hydroxide (KOH) to produce and modify activated carbon. The methods employed for activation by considering the activation process, carbonization, temperature, activation time, and KOH ratio to material are described and how the surface area, surface morphology, and functional groups are affected by the KOH ratio. Characterization techniques and preparation conditions are summarized. The activated carbon pore structure mainly depends on the burn‐off size and the time for activation is linked to the overall activation reaction rate. The increase in surface area and pore size depends on the ratio of KOH, showing that KOH affects the surface chemistry of the activated carbon. The sorbent‐sorbate interactions are strongly influenced by different parameters, which were also calculated in this review and used to evaluate such interactions.

“…So it has been shown that true selection of the biomass precursor can construct a bridge from the biomass derived materials to sustainable development. Orange peels are also used as a biomass source for activated carbon production [60]. The produced activated carbon is indicated as a very highly porous structure and its nanocomposite was produced by the combination with poly aniline.…”

Biomass is the general term for organic substances derived from living organisms (plants and animals). Since, biomass is a renewable, sustainable, innovative, low cost and carbon-neutral energy source, the applications of nano-micro particles produced from biomass in electrochemical applications have emerged. A large number of carbon-based materials, such as featured activated carbon, carbon nanotube, C-dots, biochar, hybrid carbon-metal/metal oxide … etc. can be produced from divergent types of biomass. With the growing energy need in the world, supercapacitors have also developed considerably besides the energy generation and storage methods. The supercapacitor is an energy storage system that can work reversibly to provide high energy in a short time. In these systems, electrode structure and surface properties are crucial for energy capacity enhancement. In this sense, electrode modifications with the above-mentioned biomass-based nano-micro structures are widely used in supercapacitor applications.

“…Several biomass materials have been used, such as rice husk, corn cob, eucalyptus leaf, , fruit peel, etc. To illustrate, the utilization of biomass waste like orange peel, (OP) for AC production, using various activating agents (KOH, NaOH, and H 3 PO 4 ), – is commonplace. This versatile form of carbon has found applications in diverse studies encompassing dye and HM removal, – supercapacitors, batteries, and gas sensors .…”

This study reports the development of a new electrochemical sensor based on a carbon paste electrode (CPE) composed of biomass-based orange peel activated carbon (ACOP) and multiwalled carbon nanotubes (MWCNTs), and this composite is used for the electrochemical detection of cadmium ions (Cd 2+ ). The ACOP/MWCNT composite was characterized by FTIR, Raman, and electrochemical impedance spectroscopy. The electrochemical evaluation of Cd 2+ was performed using square wave and cyclic voltammetry. The ACOP/MWCNT−CPE electrochemical sensor exhibited a coefficient of determination r 2 of 0.9907, a limit of detection of 0.91 ± 0.79 μmol L −1 , and a limit of quantification of 3.00 ± 2.60 μmol L −1 . In addition, the developed sensor can selectively detect Cd 2+ in the presence of different interferents such as Zn 2+ , Pb 2+ , Ni 2+ , Co 2+ , Cu 2+ , and Fe 2+ with a relative standard deviation (RSD) close to 100%, carried out in triplicate experiments. The ACOP/MWCNT−CPE presented high sensitivity, stability, and reproducibility and was successfully applied for the detection of Cd 2+ in river water samples with recovery rate values ranging from 97.33 to 115.6%, demonstrating to be a very promising analytical alternative for the determination of cadmium ions in this matrix.
