“…[8]. Activated carbon is considered as the most beneficial source of supercapacitor electrode material compared to the other materials due to its following advantages; effective electrical conductivity, high surface area, longer cycling life, relatively cost effective, high capacitance, good porosity, electrochemical stability and most importantly environment friendly nature [9][10][11]. Activated carbon has its precursors from various resources such as carbonaceous, agricultural and industrial materials (few examples are coal, coke, peat, petroleum, wood or coconut oil palm shells, banana fibers, corn grains, lapsi seed, needle cokes, seaweeds, sunflower shells, etc.)…”

“…Some effort have been done to look for activated carbon with high surface area and low production cost, such as the utilization of biomass waste materials [3]. Various types of biomass waste have been reported as electrodes in the supercapacitor devices such as: sugar cane bagasse [4], corncob [5], rice husk [6], coconut shell fibers [7], oil palm empty fruit bunches [8], rubber wood sawdust [9] and cassava peel [10]. A wide variety of electrode materials study shown that surface area characteristic have a linearly corelation with the capacitive properties of a supercapacitors cells.…”

Preparation and characterizations of activated carbon monolith from rubber wood and its effect on supercapacitor performances AIP Conference Proceedings 1712, 050011 (2016) Abstract. Seven types of activated carbon electrode (ACM) have been produced from the banana peel waste for supercapacitor application. The difference type of the electrode was synthesized by the various conditions of carbonization and activation. The production of the ACM was begun by the milling process and molded by a solution casting technique. The next step was followed by drying, carbonization and activation process. Physical properties of the ACM were studied by the N2 gas absorption-desorption method to characterize the specific surface area of the sample. On the other side, the electrochemical properties such as specific capacitance (Csp), specific energy (E) and specific power (P) were resulted by calculating the current (I) and voltage (V) data from the cyclic voltammetry testing. Based on the data obtained the surface area of the ACM has a significant relationship with the electrochemical properties. The specific surface area (SBET), Csp, E and P were found the maximum value as high as 581m 2 / g, 68 F/g, 0.75 Wh/kg and 31 W/kg, respectively. Further more, this paper were also analyzed the relationship between electrochemical properties of supercapacitor with the degree of crystallization of the ACM.

“…In this region the AC exhibits a sharp weight loss, which accounts around 11 % of the total weight loss. This can be attributed to the decomposition of lignin . The temperature peaks during which the maximum weight losses occurred during thermal degradation of the AC were 65, 276, and 632 °C, as shown by the derivative weight loss curves in Figure .…”

“…The second weight loss region was observed between 150–400 °C, and the weight loss in this region is around 5 %. This could be due to burnt‐out cellulose and hemicellulose components . The third weight loss region is within the temperature range of 400–800 °C.…”

The aims of this work were to prepare porous activated carbon from peanut shell by chemical activation using ZnCl2 and study its volatile organic compounds adsorption capacities. The adsorption properties of ethyl on the prepared activated carbon were experimentally determined at different temperatures. The surface textural characteristic of the activated carbon was evaluated by N2 adsorption isotherm measurements. The average BET surface area, pore size, and micro‐pore volume of the prepared activated carbon were 1025 m2/g, 0.70 nm, and 0.37 cm3/g, respectively, with narrow pore size distribution. Higher adsorption capacity of toluene on the activated carbon was observed compared to ethyl benzene and p‐xylene, in particular at low vapour concentration ranges. The experimental isotherm data were also analyzed using the Langmuir, Langmuir‐Freundlich, and multisite Langmuir isotherm model. The Langmuir‐Freundlich and multisite Langmuir model provide the best fit for volatile organic compound adsorption isotherms. In addition, the surface and thermal properties of the activated carbon were also investigated using FT‐IR, Zeta‐potential, and TGA. Overall, the peanut shell activated carbon prepared in this study exhibited comparable surface properties and adsorption performance with the available commercial activated carbons and activated carbons prepared from other various sources reported in other literature.
