“…For instance, porous carbon materials obtained from barley straw, activated using FeCl3 and urea, demonstrates an energy density of 10.7 Wh kg -1 at a power density of 720 W kg -1 [14]. Similarly, plantainbased porous carbon materials, prepared through a static air activation, exhibits a specific capacitance of 8.6 F g -1 at a current density of 4 A g -1 [15]. BBC-800-0 exhibits distinct advantages in terms of electrochemical performance, pricing, and material procurement.…”

Porous carbon materials were synthesized from bamboo shoot shells through carbonization and static air activation. The physicochemical properties of bamboo shoot shell-based porous carbon (BBC) were observed by scanning electron microscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, and N2 adsorption desorption analysis. BBC has an optimal hierarchical porous structure that displays a specific surface area of 546.04 m2 g-1 and an average pore diameter of 3.28 nm. The formation mechanism of the BBC, which has a hierarchical porous structure in static air activation, was illustrated systematically. To evaluate the suitability of BBC for practical implementations further, the constructed symmetric supercapacitor achieved an energy density of 11.11 Wh kg-1 at a power density of 252 W kg-1 and an outstanding cyclic retention rate of 100% over 7,000 cycles at a current density of 10 A g-1.

“…The conventional carbon-based materials like graphene or carbon nanotubes are quite expensive due to their rarity and complex synthesis preparation therefore, it is urgently necessary to nd alternative materials for commercial carbon materials. The biowaste can be converted into the high value-porous activated carbon with large speci c surface area that is commonly used for several kinds of applications such as adsorbent [16,17], catalyst [18,19], to energy storage systems [20][21][22][23]. Compared to commercial carbon materials, activated carbon-based biowaste can be synthesized by the facile process through hydrothermal [24,25], chemical activation [26-28], or pyrolysis carbonization [29][30][31].…”

A well-developed porous activated carbon materials were synthesized from palm kernel shell (PKS) waste through the facile carbonization process with several KOH concentration, and the microwave absorbing performance were studied in the X-band range. The XRD and EDX measurement results confirmed the transformation from crystalline structure to the amorphous structure of cellulose of PKS materials with the higher carbon content. The BET analysis measures the pore size between 2–4 nm and a specific surface area between 554–825 m2/g. All activated carbon materials show the improvement of microwave absorbing performance compared to its hydro char or raw PKS materials, with the highest minimum return loss and frequency bandwidth of -37.85 dB at 11.02 GHz and 900 MHz, respectively, for activated carbon with only KOH concentration of 10%. The porous structure of AC-based PKS is benefitted to give better impedance matching and dielectric loss capacity to enhance the microwave absorbing performance of AC-based PKS waste. This observation indicates that the activated carbon can be synthesized with a facile process from PKS waste and expands the possible utilization of AC-based PKS waste as the prospective microwave absorber materials for electronics and telecommunication devices.
