A theoretical approach to Nanotechnology and synthesis of CNT by renewable natural precursor and their applications studied at our center

Carbon-based nanomaterials like carbon nanotube, carbon nanobeads, DLC, low band gap semiconducting carbon etc, would be the material of 21st century for various applications. Presently these materials are being synthesized from various precursors like graphite, methane, benzene etc; all of these materials are directly or indirectly related to fossil fuels. Any technology based on these materials would suffer a big blow once these precursors are depleted. It is therefore, most essentials that we develop a synthetic rout for carbon novel materials from precursor, which is renewable and is not related to fossil fuels. Camphor is one of the natural sources derived from the resin of pine trees or from the resin of camphorea tree (Cinnamomum C Camphora). These trees can be grown as and when needed. Thus camphor becomes a true renewable precursor for carbon novel material, provided we can establish the technology to synthesize various carbon nanomaterials from it. Our group has been able to synthesize almost all forms of carbon novel materials from camphor. During this lecture, it would be my efforts to discuss the various products synthesized from camphor and also discuss how camphor is superior to conventional carbon precursors. Finally applications of these materials specially, electron-field emission, lithium battery, carbon solar cell, killing cancerous cell, will be discussed.
