Abstract

Hybrid of magnetic and silver nanoparticle decorated-reduced graphene oxide (Fe₃O₄@RGO and Ag@RGO) have been prepared with the aid of poly(ionic liquid) (PIL) as a versatile coupling agent. The hybrid materials of Fe₃O₄@RGO/PIL or Ag@RGO/PIL were assembled into 3D-architectured nanostructures. By means of spray layer-by-layer technique, the sensor array based on those composites has been fabricated and exploited to detect diverse volatile organic compounds (VOCs). The sensor exhibits superior sensing response to graphene only - based sensors by improving both sensitivity and selectivity towards a set of standard VOCs.
