“…During this process, micro‐, meso‐ and macro‐pores were simultaneously generated, which could work together to increase the specific capacitance. However, the excessive use of potassium hydroxide can cause porous structure to collapse and form carbon sheets . The final carbon samples are named as EWC−X (X represents the mass of the added KOH).…”

Using egg white as raw material, the activated carbon materials with nitrogen doping were synthesized by a two‐step method involving carbonization and activation. Structure characterization showed this porous carbon had a three‐dimensional honeycomb structure composed of interconnected micropores and mesopores, which resulted in a high specific surface area of 2918 m2 g−1. Due to KOH activation, the appropriate ratio of micropore to mesopore could optimize the diffusion channel of electrolyte ion and increase the contact area between electrolyte and electrode. Thus the egg white‐derived porous carbon (EWC) showed outstanding electrochemical properties as supercapacitor electrode. In three‐electrode system, a high specific capacitance of 335 F g−1 could be achieved at a current density of 0.5 A g−1, and only 8.3% of capacitance was lost after 10000 cycles. For the symmetrical supercapacitor fabricated with as‐prepared carbon material, it exhibited a specific capacitance of 68 F g−1 and a maximum energy density of 13.6 W h kg−1.

“…The production of porous carbon from lignocellulosic material has been widely studied. There are the production of porous carbon from coconut shell, mangosteen rind, corn cob, bagasse, durian rind [2,3,8]. From the several previous studies, the mangosteen rinds has the potential as a raw material for the preparation of porous carbon with high surface area so that it can be used as an adsorbent with the large capacity [6,8].…”

Abstract.Mangosteen rind is an important source of natural antioxidants. Due to the growing interest in extracting this anti cancer substances from the mangosteen rind, the amount of this lignocellulosic residu has been generated significantly as byproduct. In this research, extraction-waste mangosteen rind (EMP) was used as alternative precusor for production of carbon-based adsorbent for ethylene removal. Steam was used as activating agent and the effect of carbonization time and temperature on the development of pore structure were examined. Pyrolysis process was carried out by heating the mangosteen rinds powder (180 μm -355 μm) from ambient temperature up to carbonization temperature of 848 K and kept for 3 hours then followed by heating up to 1123 K and kept for 15 minutes under flowing N2 and steam. This process was repeated for several pyrolysis temperature (1053 K, 1073 K, 1083 K and 1103 K) and carbonization time (0 hours, 1 hour, 2 hours, and 3,5 hours). The carbon obtained was characterized in terms of its pore structure and ethylene uptake capacity. The results show that porous carbon obtained from pyrolysis of extraction-waste mangosteen rind can be characterized as mesoporous carbon. The highest surface area of 1080 m 2 /g was obtained from pyrolysis of extraction-waste mangosteen rinds with carbonization time of 3.5 hours and pyrolysis temperature of 1123 K. Furthermore, the mesopore portion and the specific surface area increased with the increasing carbonization time. From the ethylene uptake experiment, it was noted that the ethylene adsorption capacity of EMPC is 40.12 cm 3 /g.
