摘要：

In the present study synthesis of reduced graphene oxide using L-citrulline and its application for detection of 10 ppm concentration of NO and 1% Hydrogen gas at 50 and 100 degrees C temperature are reported. Characterization by XRD, Raman spectroscopy and FTIR provide strong evidence for reduction of GO. The reduced graphene oxide (rGO) exhibited wrinkle structure indicating its suitability for gas sensing. Further, reduced graphene oxide shows 4.1% and 9.5% response for 10 ppm concentration of NO gas at 50 and 100 degrees C respectively. The response was 0.87% for 1% H-2 gas at 50 degrees C and 2.07% at 100 degrees C. This investigation indicates the usefulness of green synthesized rGO for gas sensing. (C) 2018 Elsevier B.V.
