Synthesis and characterization of activated carbon from jute fibers for hydrogen storage

Abstract

Abstract. Activated carbons (ACs) are being used as energy storage material especially for hydrogen storage application. In the present work, AC materials were synthesized from jute fibers, activated and treated using KOH to increase the porosity of samples. These AC samples retained the fibrous structure even after chemical activation at high temperature of 700°C. Channel like structures were formed which helps to increase the hydrogen storage capacity. The surface area of these samples varied from 380 to 1220 m 2 /g due to carbonization and activation treatment. The sample with high surface area of 1224 m 2 /g showed a high hydrogen uptake capacity of 1.2 wt.% at 30°C and 40 bar of H 2 gas pressure. This sample also showed a high pore volume of 0.74 cm 3 /g. These results indicate that the raw material jute fibers can be used as hydrogen storage medium after thermal and chemical treatment which increases the surface area and micropore volume.

Preparation and Utilization of Jute‐Derived Carbon: A Short Review

“…In addition to carbohydrates, both contain a trace amount of fat (1.9 % in stick and 0.3 % in fiber) and ash content ( � 1 % in stick and 0.6-2 % in fiber). [39][40][41][42] Likewise, they have a similar percentage of hemicellulose ( � 22 %) and different percentages of cellulose (~40.8 % in stick and 65.0 % in fiber) and lignin (23.5…”

Jute-derived microporous/mesoporous carbon with ultra-high surface area using a chemical activation process

“…In addition, activated porous biocarbons using single-step activation have been reported. [43][44][45][46] However, considering the limited research utilizing jute biomass, the surface area is confined between 400-1000 m 2 •g -1 for physically activated carbon [47,48] and 800-1200 m 2 •g -1 for chemically activated carbon [49,50] .…”

“…Very few reports have highlighted the conversion of jute fiber into valuable activated carbon using easy, inexpensive and scalable synthesis techniques. [47][48][49][50] At the same time reports on the…”

“…Additionally, the maximum surface area generated using jute-and jute-related precursors is less than 1200 m 2 •g -1 . [50] In this study, we synthesized NCs from three different parts of jute fibers through a chemical activation method using KOH. Nitrogen adsorption-desorption isotherms, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, UV spectroscopy, and scanning/transmission electron microscopy (SEM/TEM) were performed to characterize the morphology and porous structure of the obtained NCs.…”

Preparation and properties of carbon‐fiber‐ and pine‐cone‐fiber‐reinforced high‐density polyethylene composites

“…Compared with synthetic fibers, natural fibers have advantages of wider sources, lower prices, less loss, and lower device damage in manufacturing; are environmentally friendly; and can be used repeatedly. 2 So far, extensive research on WPCs of different nonwood natural-plant-fiber-reinforced composites has been reported, [3][4][5][6][7][8] and some composites have been commercialized.…”
