Abstract

To develop a low-cost and highly efficient photocatalyst under the visible illumination, Ni₃Fe-CO₃-LDH (referred to hereafter as NiFe-layered double hydroxide or NiFe-LDH) was used as a precursor to synthesize Fe₂O₃-NiO-Cr₂O₃ composite. The NiFe-LDH was prepared by co-precipitation and then it was exchanged with dichromate. After calcining at 600°C, the Fe₂O₃-NiO-Cr₂O₃ composite was obtained. The composites' absorption edge intensely extended up to ca. 700nm covering the full visible light spectrum and showed high catalytic activity at natural pH under the visible light illumination. A very high methylene blue degradation of 91.2% was achieved with the aid of H₂O₂ in 120min with no detectable Cr in solution.
