摘要：

In the present work, room temperature hydrogen sensing properties of platinum (Pt) and platinum iron (Pt3Fe) alloy nanoparticle (NP) decorated nitrogen doped graphene were investigated. In order to incorporate the nitrogen functional groups within the graphene matrix, first graphene was coated with the nitrogen anionic polyelectrolyte followed by the pyrolysis in inert atmosphere. Further Pt and Pt3Fe nanoparticles were decorated on nitrogen-doped graphene (NG) by modified polyol reduction technique. The systemic investigation of hydrogen sensing properties of Pt/NG and Pt3Fe/NG NPs at 4 vol% of hydrogen reveals the excellent sensitivity of these composites. The present study shows that Pt3Fe/NG NPs composite can be believed as a high performance room temperature sensing material. Copyright (C) 2015, Hydrogen Energy Publications, LLC.
