Polypyrrole-bonded quaternary semiconductor licumo2o11-graphene nanocomposite for a narrow band gap energy effect and its gas-sensing performance

In this study, we demonstrate the fabrication and characterization of a new quaternary semiconductor nanocomposite of LiCuMo2O11/graphene oxide/polypyrrole (LCMGP) via a hydrothermal method and testing of an NH3 and H2SO4 sensor operating in gaseous states at room temperature. We used X-ray diffract...
