Abstract
AbstractA reduced graphene oxide (RGO) and polypyrrole (PPY) nanofiber composite was fabricated using a one‐step redox reaction under UV illumination at room temperature. Graphite oxide (GO) was effectively reduced to RGO without any chemical agent during the formation of the polypyrrole nanofibers. The RGO–PPY nanofiber composite showed four times higher NO2 sensitivity than that of RGO alone. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
