TL;DR: In this paper, karanj (Pongamia pinnata ) fruit hulls were used as a precursor to prepare low-cost activated carbon with a large surface area through KOH activation.
Abstract: In this study, karanj ( Pongamia pinnata ) fruit hulls were used as a precursor to prepare low-cost activated carbon with a large surface area through KOH activation. The prepared activated carbon (KFHAC) was characterized through pore structural analysis, scanning electron microscopy, and Fourier transform infrared spectroscopy. KFHAC presents a BET surface area of 828.30 m 2 /g, a micropore volume of 0.36 cm 3 /g, and an average pore size of 19.92 A The adsorption performance of KFHAC was evaluated using methylene blue (MB) as the model adsorbate. Adsorption experiments indicated that the pseudo-second-order kinetic and Langmuir adsorption isotherm models can accurately describe the adsorption process. The maximum adsorption capacities ( q m ) of MB were 154.8, 203.4, and 239.4 mg/g at 30 °C, 40 °C, and 50 °C, respectively. This study indicates that karanj fruit hull is a promising precursor for the production of low-cost and efficient activated carbon with a large surface area.

TL;DR: In this article, the pore structure of steam-activated carbon was characterized by the t-plot method based on N2 adsorption isotherms and the results indicated that the observed increase in double-layer capacitance arises mainly from the development of mesopores.
