Enhancement of heterogeneous photo-Fenton performance of core-shell structured boron-doped reduced graphene oxide wrapped magnetical Fe3O4 nanoparticles: Fe(II)/Fe(III) redox and mechanism
In this paper, a kind of novel core-shell structured heterogeneous photo-Fenton catalyst, boron-doped reduced graphene oxide wrapped Fe3O4 (Fe3O4@B-rGO) composite, was successfully synthesized by heating the mixture of Borane-Tetrahydrofuran adduct and graphene oxide wrapped Fe3O4 (Fe3O4@GO) under reflux conditions. The core-shell structure of the catalyst had been confirmed by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photo electron spectra (XPS), and electron energy loss spectrum (EELS). The experimental results for Bisphenol A (BPA) degradation demonstrated that the as-prepared catalyst exhibited much higher photo-Fenton catalytic activity than Fe3O4 and reduced graphene oxide wrapped Fe3O4(Fe3O4@rGO). Additionally, Fe3O4@B-rGO with mass concentration of doped boron at 9.3% exhibited the optimum catalytic property, in which system the BPA degradation kinetic rate constant was almost 1.96 times and 1.82 times of that in the systems with Fe3O4 and Fe3O4@rGO, respectively. Finally, the mechanism analyses verified that center dot OH, O-2(center dot-) and h(+) were the main reaction species in this system, and photo-electron generated by boron doped reduce graphene oxide (B-rGO) can accelerate the redox between Fe(II) and Fe(III). The excellent photo-Fenton performance, stability and magnetic separation properties make it promising for the degradation of organic compounds in waste water under visible light.
