Structural and Optoelectronic Properties of Nano Carbons Synthesized by Simple Pyrolysis of Bamboo

Abstract

Nano carbon today is an attractive material with excellent optoelectronic and thermal properties. It has found huge interest in electronic industries. This study reports the synthesis of nano carbon from two different bamboo precursors; Bambora arundi nacfau and Bambosa nafau, available in Indian forests. Synthesis of nano carbon materials have been carried out by simple pyrolysis technique by carbonizing the bamboo pieces in a furnace at 600 °C in atmospheric condition with heating rate of 10°/min and stand at this temperature for 30 min. Different properties were investigated by means of X ray diffraction, UV-VIS Spectrophotometric and Hall Effect measurements. Absorbance was found to be below 20% for dispersed nano particles. From crystallographic analysis (XRD) formation of graphite was observed only in Bambosa nafau. Apart from these three prominent peaks at 28.13, 40.34 and 50.08° were observed that could be attributed to residual matrix. The nano carbons synthesized from two different bamboos were compared in terms of their structure, light absorption in UV-VIS region and electrical properties. The as grown carbons showed resistivity in the range of 10⁴–10⁵ Ω-cm.
