N2 - The novel photocatalyst of α-Fe 2O 3/Sb-doped SnO 2 (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-Fe 2O 3/Sb-doped SnO 2 nanocomposites have better photocatalytic activities than α-Fe 2O 3/SnO 2 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.
