Selective reduction of graphite oxide: a novel approach

Graphite oxide (GO) has been selectively reduced (SGO) by H+/Na/methanol for conversion of -COOH to -OH groups. Enhanced H-bonding is confirmed between SGO and bistartratocuprate(II)(4-) via FTIR. The graphene/copper nanocomposite subsequently prepared by its in situ reduction showed superior EMI shielding properties compared to conventionally obtained nanocomposites.
