Abstract

Owing to the electron donor–acceptor properties of GO, the active sites ([triple bond, length as m-dash]Fe2+) of Fe3O4 are not oxidised ([triple bond, length as m-dash]Fe3+) in the heterogeneous Fenton-like reaction. GO plays a sacrificial role via the oxidation of (C[double bond, length as m-dash]C) carbon domains, and transferring electrons to Fe3O4. Therefore, GO–Fe3O4 confers superior catalytic efficiency, recyclability and longevity, otherwise not available in Fe3O4.
