Abstract


Uniform and magnetic recyclable hollowsphere Zn doped Fe3O4 were successfully synthesized via simple one-pot solvothermal route. Morphology and structure of as-obtained products was characterized by XRD, SEM, HRTEM methods. The Zn-doped Fe3O4 hollowsphere exhibited high photocatalytic activity for degradation of hexavalent chromium under visible light irradiation. The effects of reaction conditions such as initial pH, photocatalyst dosage and hexavalent chromium contratentation were also studied systematically. The stability of the catalysts and and possible catalytic mechanism was also proposed. The results indicate that Zn doped Fe3O4 can be promising catalyst for photo-reduction of hexavalent chromium.

Keywords
