Preparation and Photocatalytic Activities of α-Fe₂O₃/Sb-doped SnO₂ (ATO) Nanocomposites

Abstract:

The novel photocatalyst of α-Fe₂O₃/Sb-doped SnO₂ (ATO) nanocomposites were fabricated by two-step process of hydrothermal and precipitation method. The structure, size, magnetic behavior and absorption property were characterized by XRD, TEM, VSM and UV-Vis absorption spectrum. The composites with low mole ratio of ATO have more pronounced photocatalytic activities. The optimum photocatalytic activity in our experiments appears at the mole ratio of n_Fe:n_Sn=1:0.25. The α-Fe₂O₃/Sb-doped SnO₂ nanocomposites have better photocatalytic activities than α-Fe₂O₃/SnO₂ nanocomposites. The results show that the doping of Sb ions can improve the capture ability of electrons and consequently enhance the photocatalytic activities of the composite system.
