“…Here, the adsorbents are highly mesoporous in which capillary condensation occurs. This result indicates that the pore structure of the carbon can be tailored by controlling the activation temperature as also reported by Li et al [11]. Although, the same temperature of 600 °C was used in all the experiments in this study, but the activation may be considered as a "double pyrolysis" since it was also carried out at 600 °C.…”

“…The produced pyrochar properties are mostly based on the pyrolysis conditions and the raw material being used [9]. Feedstock suitable to produce pyrochar (used in MFC) are oxygen-rich biogenic material such as corncob (carbon content -CC of 46.5 %), rice husk (27 % CC), peanut shell (45.3 % CC), vinery waste (48.7 % CC) and kraft lignin (56 % CC) [10,11]. Furthermore, a higher specific surface area (SABET) and pore development during pyrolysis is usually achieved through carbon activation process.…”

Despite large varieties of commercially available electrodes, only few are suitable for electro-active bacterial colonization during biofilm formation in microbial fuel cells (MFCs), and most of these electrodes are cost prohibitive. Hence there is need to search for low-cost alternative electrodes for MFCs. Pyrochars were produced in this study by pyrolysis (600 °C and a continuous flow rate of 3 L/min of nitrogen gas for 30 min) and subsequently steam and potassium hydroxide (KOH) activation of the pyrochar at 600 °C were carried out accordingly. Physicochemical, structural, and electrochemical properties of the activated and non-activated pyrochars were determined according to standardized analytical methods. According to BET, 1626 m 2 g -1 surface area and 14.74 Å pore diameter were obtained from the KOH-activated pyrochar which was also the most conductive (0.26 S m -1 ). Chemical activation of pyrochar with KOH resulted in increased electrical conductivity (EC), pore diameter, and most importantly the material's surface area according to the findings. In conclusion, KOH-activated corncob pyrochar holds potentials for producing electrode materials with desirable characteristics for successful application in MFC compared to the non-activated and steam-activated pyrochars of the same biomass.
