Synthesis of Carbon Nano Fiber from Organic Waste and Activation of its Surface Area

Abstract

Carbon Nano fi bers (CNFs) have recently attracted a lot of attention due to their widespread range of technological applications attributed to their unique physical and chemical properties, such as, small size, high strength, high adsorption linked with their large specifi c surface area, high temperature tolerance and corrosion resistance. CNFs have been used in energy conversion and storage, reinforcement of composites and self-sensing devices. The complete removal of entrapped metallic impurities and amorphous carbon incorporated with CNFs has been a long-standing issue. We have developed a new approach for preparing graphitic CNFs and its activation of surface area by purifi cation. This approach entails Thermal Decomposition (TD) based synthesis of CNFs from organic solid waste, such as, stems of rice plants. CNFs are synthesized from organic waste precursor (Rice Stems) at 900 o C under inert atmosphere. The active surface area was measured using a Surface Area Analyzer. Morphology of CNFs was studied with using SEM and XRD. The SEM image shows that the synthesized CNFs have diameter ranging within 45-60 nm.

“…Antisymmetric and symmetric bending vibrations of CH 3 are attributed to the bands at 1454 and 1382 cm −1 28 . Moreover, the FT‐IR results (Figure S4) show that CNF has CC, CO, and CN binding stretching which was indicated by peaks at 868, 754, and 680 cm −1 in the fingerprint region 66 …”

“…28 Moreover, the FT-IR results (Figure S4) show that CNF has C C, C O, and C N binding stretching which was indicated by peaks at 868, 754, and 680 cm À1 in the fingerprint region. 66 Thermal properties of 5%-15% GRP/PLA 3D electrodes were investigated by thermogravimetry analysis (TGA) in an argon atmosphere. The Figure S5 is represented the obtained TGA curves for 5%-15% GRP/PLA 3D electrodes.…”
