few layered graphene sheets. This technique is based on the reduction of graphite oxide to
graphene by exfoliation in the presence of hydrogen gas rather than the conventional
thermal exfoliation method. GO was prepared according to Hummers' method and also by a
modified Hummers' method (MH method). … In summary, we have presented a new and
easy technique for the rapid and large scale synthesis of exfoliated graphene sheets. The …
