One-step Preparation and UV-Fenton Properties of Fe3O4/TiO2@Bio-carbon Composities†

Abstract

Abstract:

A novel maize straw carbon(MSC) skeleton layered mesoporous material, Fe₃O₄/TiO₂@MSC, was synthesized by using maize straw as raw material and calcination with iron salt and titanium salt solution. The degradation of tetracycline hydrochloride(TCH) in UV-Fenton system was studied. The as-synthesized catalysts were characterized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), N₂ adsorption-desorption, scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The results showed that the prepared Fe₃O₄/TiO₂@MSC retained the original pore morphology of maize straw. The nano-Fe₃O₄ and TiO₂ grew on the surface of MSC. The straw carbon as a framework improved the dispersion of nano-Fe₃O₄, prevented its agglomeration, increased the stability of catalyst, and increased the specific surface area and active site of the material, thereby enhancing the UV-Fenton’s reactivity. The synergistic effect of TiO₂ photocatalysis and UV-Fenton system can promote the conversion of Fe(Ⅲ) to Fe(Ⅱ). Therefore, under the same conditions, TCH degradation efficiency in Fe₃O₄/TiO₂@MSC catalyzed UV-Fenton system reached 99. 8% after 40 min reaction, much higher than those in Fe₃O₄@MSC+H₂O₂(30%), UV+H₂O₂(73%), UV+Fe₃O₄@MSC+H₂O₂(89.1%) and UV+Fe₃O₄/TiO₂+H₂O₂(89.2%) systems. And the system can achieve satisfactory removal effect under neutral or even alkaline conditions.
