摘要：
A direct Z-scheme type alpha-Fe2O3/FeVO4 heterostructured photocatalyst with novel nanobelt structure just like the leaves of bryophyllum pinnatum has been successfully synthesized for the first time via integrating a facile electrospinning with annealing procedure. The as-prepared products are characterized by XRD, FT-IR, XPS, SEM, TEM, HRTEM, BET, PL, TOC, HPLC, EIS, Micro-Raman and UV-vis absorbance spectroscopy.The photocatalytic activity of alpha-Fe2O3/FeVO4 nanobelts evaluated by themethylene blue (MB) degradation under visible light irradiation could be ascribed to the extended light absorption and improved charge separation efficiency. A reasonable Z-scheme photocatalytic mechanism is proposed on the basis of structural and electrochemical characterization, which could well explain the enhanced migration rate of photogenerated carriers in alpha-Fe2O3/FeVO4 heterojunctions.
