“…In recent years, activated carbon is considered to be an ideal electrode material because of its large specific surface area, porous structure, strong adsorption, stable chemical properties and regeneration etc. and Dinesh [31] used bamboo as precursor and KOH as activator to synthesize nano activated carbon under nitrogen atmosphere, and to increase the surface area and pore size performance of electrodes. Han et al [32] prepared high specific surface area-based activated carbon from pepper straw using chemical activation method, and the GAC (granular activated carbon) made under certain conditions has a specific surface area of 743.429 m2/g and a specific capacitance of 262.595 F/g.…”

In recent years, the electro-sorption technology (EST) has been increasingly applied in the field of water treatment. Firstly, this paper conducts a review on the development history of the EST theory from the classic models (Helmholtz-Perrin model, Gouy-Chapman (GC) model, and Gouy-Chapman-Stern (GCS) model) to the modern electrical double layer (EDL) models (Grahame, electrical triple-layer model, and composite model) as well as the recent status of the theoretical research. Besides, the future development direction and research focus of the EST theoretical model were given. Finally, the current research status of carbon electrodes, metal oxide electrodes and composite electrodes was summarized. This study shall provide theoretical supports for practical application of high-efficiency EST, and the direction for the future development of EST-based electrode materials.

The current study involves the value-based conversion of waste floral foam into nanoporous activated carbon (NAC), which can be employed as a bifunctional material as a CO 2 adsorbent and an electrode for supercapacitors. The waste floral foam is first subjected to acid pickling and then thermally activated at various temperatures (500−800 °C) under a N 2 atmosphere. The resultant optimum sample, NAC700, has a high surface area of 732 m 2 /g, an abundance of narrow micropores (≤0.8 nm), and rich surface oxygen functionality. Owing to its array of synergistic attributes, the optimum sample NAC700 exhibits an excellent CO 2 capture capacity of 3.22 mmol/g at 15 °C and 1 bar. Simultaneously, NAC700 also delivers a good specific capacitance of 116 F/g at 5 mV/s and 187 F/g at 0.2 A/g, as calculated from CV and GCD data, respectively, in 1 M KOH. The strategy proposed here offers a facile pore manipulation technique for fabricating nanoporous activated carbon with substantial potential for CO 2 capture and energy storage applications while neutralizing waste floral foam.

“…Because of its ability to store data quickly, SCs have attracted more interest than batteries, a Supercapacitor with the same weight as a battery can hold more power and enhanced cyclic stability. Aside from low energy density, new advances in SC electrolytes and electrode materials have the potential to bridge the gap between fuel cells and batteries and conventional electrolytic-capacitor technology [2]. The material used to build a supercapacitor's electrodes and the electrolyte that delivers the greatest results for each electrode define the supercapacitor's efficiency.…”

The electrode materials for supercapacitors based on biomass-produced Rice Husk Activated Carbon (RHAC) and RHAC+50% MgO nanocomposite are compared in this article. The crystallinity, structural morphology, and crystalline size of the particles were determined using microstructural and electrochemical characterization. Scanning Electron Microscope and X-Ray Diffraction techniques were used to determine the surface morphology and crystallinity of the materials. The XRD results reveal that RHAC which has broad peaks indicates amorphous nature whereas RHAC+50% MgO nanocomposite which has sharp peaks exhibits crystalline nature. The RHAC+50% MgO nanocomposite electrode exhibits a specific capacitance of 220.52 F/g however RHAC electrode exhibited only 162.91 F/g at a scan rate of 2mV/s by Cyclic Voltammetry in 1 M KOH electrolyte. After 2500 cycles of Galvanic charge-discharge, it was discovered that RHAC+50% MgO nanocomposite has capacitance retention of 76.71% and RHAC has capacitance retention of 80.49%.
