Description
A facile method for reducing graphite oxide (GO) using γ-irradiation is explored without using any photocatalysts or reducing agents. The obtained reduced graphene oxide (r-GO) is investigated by XRD, TEM, FT-IR. Various spectroscopic and imaging techniques confirm that most of the chemical functional groups present on GO are removed by irradiation, and Au nanoparticles are deposited on r-GO sheets which prevents the aggregation of Au nanoparticles.The size of nanoparticles increases with increasing Au3+ doping level. Moreover, the catalytic activity of the r-GO/Au nanocomposites is also investigated.
