Abstract

Graphene oxide (GO) synthesized from a modified Hummer's method was reduced (referred, rGO) by using 100 MeV Au ion species and its response to the sense H₂O₂ was investigated. The changes in the atomic composition and structural properties of rGO after irradiation were studied using x-ray diffraction, Fourier transform infrared spectroscopy and x-ray photo-electron spectroscopy. These results suggested that the removal of the oxygen-containing functional groups and the improvement of the electrochemical performance of reduced graphene oxide (rGO) after ion irradiation. Raman spectroscopic results revealed the increase in the disorder parameter (I _D/I _G) after Au ion irradiation and also the formation of a large number of small sp² domains due to the electronic energy loss of ion beam. The resultant rGO was investigated for H₂O₂ sensing using electrochemical techniques and it showed a good response.
