“…Activated carbon is a well-known porous material with large surface area and pore volume, and is extensively used for gas separation, solvent recovery, contaminant removal from water, wastewater treatment, and as a catalyst/catalyst support for different energy storage and conversion processes [1]. Recently, activated carbon has been extensively investigated for making carbon foams [2] and ultracapacitors/supercapacitors [3,4] due to its porous structure.…”

“…As the pore properties of activated carbon largely depend on the precursor materials and the synthesis method, different types of materials (natural and synthetic) have been examined as precursors. The most commonly used precursors for activated carbon production are coal, coconut shell, wood, agricultural wastes, or industrial wastes [1]. Among them, biomass as a precursor is attracting significant attention as it is renewable, abundant, low cost, and eco-friendly.…”

Synthesis of activated carbon from waste biomass is of current interest towards sustainability. The properties of biomass-derived activated carbon largely depend on the carbonization process. This study reports the preparation of mesoporous activated carbon with extremely high surface area from hemp bast fiber using hydrothermal processing. Hot water processing (390-500 • C) followed by activation using KOH and NaOH was investigated at different mass ratios. The described approach was found to enhance the mesoporosity (centered at 3.0 to 4.5 nm) of the hemp-derived activated carbon (HAC) from activation [confirmed by BJH (Barrett-Joyner-Halenda) pore size distribution and TEM (transmission electron microscopy) imaging]. BET (Brunauer-Emmett-Teller) results showed that the product has an extremely high surface area (2425 m 2 /g) while the surface functional groups (-OH, -COOH, C=C/C-C) were confirmed by FTIR (Fourier transform infrared spectroscopy) and further quantified by XPS (X-ray photoelectron spectroscopy). Increasing KOH concentration was found to enhance the surface area with a maximum biochar-to-KOH (g/g) ratio of 1:3. The crystallite domain size of HAC was determined using Raman spectroscopy of different wavelengths. The procedure described in this study is an environmentally friendly scalable route for the mass production of activated carbon using hemp fiber.

Synthesis of activated carbon from waste biomass is of current interest towards sustainability.The properties of biomass derived activated carbon largely depends on the carbonization process. This study reports preparing extremel high surface area mesoporous activated carbon from hemp bast fibre using hydrothermal processing. Processing in hot water (390-500 o C), then activation using KOH and NaOH was investigated at different loading ratios. The described approach was found to enhance the mesoporosity (centered at 3.0 to 4.5 nm) of the hemp derived activated carbon (HAC) from activation (confirmed by BJH pore size distribution and TEM imaging). BET results showed that the product has an extremely high surface area (2425 m 2 /g) while the surface functional groups (-OH, COOH, C=C/C-C) were confirmed and quantified by XPS and FTIR results. Increasing KOH concentration was found to enhance the surface area with an optimum biochar to KOH ratio of 1:3. The crystallite domain size of HAC was determined using Raman spectroscopy of different wavelengths. The procedure described in this study is an environmentally friendly scalable route for the mass production of activated carbon using hemp fiber.
