Owing to the electron donor-acceptor properties of GO, the active sites ([triple bond, length as m-dash]Fe(2+)) of Fe3O4 are not oxidised ([triple bond, length as m-dash]Fe(3+)) 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.
由于氧化石墨烯（GO）的电子供体-受体特性，在非均相类芬顿反应中，四氧化三铁（Fe3O4）的活性位点（[三键，长度为m破折号]Fe(2+)）不会被氧化（[三键，长度为m破折号]Fe(3+)）。GO通过（C[双键，长度为m破折号]C）碳域的氧化起牺牲作用，并将电子转移到Fe3O4。因此，GO-Fe3O4具有卓越的催化效率、可回收性和寿命，而这些是Fe3O4所不具备的。
