Preparation, Characterization of Fe₃O₄/TiO₂/CuO Nanohybrid and its Potential Performance for Chromium Removal from Aqueous Solution

Abstract:

Fe₃O₄/TiO₂ and Fe₃O₄/CuO nanohybrid nanohybrid materials have attracted widespread attention due to their scientific and technological importance as photocatalyst. Complicated process is usually used to synthesize these nanohybrid. In this study, we demonstrated a simple low-temperature sol-gel method to prepare Fe₃O₄/TiO₂/CuO nanohybrid as photocatalyst. Hexavalent chromium was used as a model pollutant to evaluate their photocatalytic activity. The results of the photoreduction of hexavalent chromium in aqueous solution indicated that with the incorporation of CuO content in Fe₃O₄/TiO₂ nanohybrid increasing the photocatalytic performance in ultraviolet and visible region. Moreover, it is found that hydroxyl radical has an important role in photocatalytic efficiency.
