Green synthesis of carbon nanotubes from agricultural wastes: A review on pathways, challenges, and future prospects
Author(s): Akrity Singh Bharadwaj, Gautam Kumar and Justin Masih
Abstract: Carbon nanotubes (CNTs) are among the most important nanomaterials that have been found in the last thirty years because of their exceptional mechanical strength, high aspect ratio, thermal stability, and special electrical characteristics. Although hydrocarbon gases, petroleum-derived products, or graphite electrodes are frequently used in conventional synthesis pathways, these methods are energy-intensive and unsustainable for the environment. Agro-based residues have become a cheap, renewable, and carbon-rich substitute for CNT synthesis in recent years. This study summarizes the state of research worldwide on the use of typical agricultural wastes, such as rice hulls, coconut wastes, corn cobs, sugarcane bagasse, and palm leftovers, for the synthesis of carbon nanotubes. In addition to structural characterization approaches, the topic includes precursor properties and synthesis processes such pyrolysis, chemical activation, arc discharge, laser ablation, and selective chemical vapor deposition (CVD). Tables and schematic representations are used to help the comparative examination of the yields, structures, and properties of CNTs obtained from agriculture. Additionally highlighted are the uses of carbon nanotubes (CNTs) derived from biomass in the fields of biomedical, energy storage, environmental remediation, catalysis, and composites. Lastly, the paper discusses the present issues with consistency, scalability, and purification while providing guidance for future approaches to combining advanced nanomaterial production and biomass waste management.
