Abstract: A hydrogen gas sensor based on three dimensional graphene/polyaniline (3D-rGO/PANI) hybrid were presented.PANI nanofibers were anchored on the surface of 3D-rGO sheets by using 3D-rGO as templates.The developed hybrid was characterized by SEM,FT-IR and BET analysis.H2 gas sensing performance of hybrid was studied and compared with that of sensor based on bare PANI nanofibers.It shown that the synergetic behavior and large surface area of hybrid allowed excellent sensitivity.3D-rGO/PANI sensor showed better response to H2 gas than that of bare PANI nanofiber.The sensitivity could reach 10.6 for H2 of 500×10-6.
