Synthesis of Fe2(MoO4)3 microspheres by self-assembly and photocatalytic performances
Abstract
Fe2(MoO4)3 microspheres were synthesized by a hydrothermal method. The Fe2(MoO4)3 microspheres showed highly efficient photocatalytic activity for the degradation of methylene blue under visible light irradiation. Kinetic studies using radical scavenger technologies suggested that holes were the dominant photo-oxidants. On the basis of the experiment results, the difference in photocatalytic activities of the Fe2(MoO4)3 samples were mainly attributed to the defects, which could act as inactivation centers, reducing the total photocatalytic activity significantly.
