ABSTRACT
Nanotechnology deals with structures of 100 nm and involves developing materials or devices within this range. Modern nanotechnology techniques lead to synthesize the metallic/ nonmetallic particles of nanosize dimensions to play a vital role in many different scienti c regimes and technological areas, particularly in the energy-related science and technology (Sadhik Basha 2014). The size of the nanoparticle overcomes the dif culties of settling, abrasion, and clogging compared to that of microsized particles (Wickham et al. 2006). The research community is actively questing hundreds of applications of nanotechnology in the prominent domain of bionanotechnology, nanostructured catalysts, and carbon-based nanomaterials. Carbon is one of the most environmentfriendly and versatile elements profusely found in various states in our earth. The application of carbon materials dates back from the past decades, sighting a speedy scienti c importance incited by the innovations in carbon-based materials. Carbon-based materials include the elemental carbon in various allotropic forms, carbon composites, and currently those materials play a vital role in the advancement of nanotechnology. The major advantages of carbon-based materials are surface functionalization, unique morphology, and chemical versatility. One of the potential applications of carbon-based materials is the carbon nanotube (CNT).
