High photocatalytic activity and photoluminescence property of hollow CdMoO4 microspheres

CdMoO4 hollow microspheres 5 μm in diameter with an interior diameter of 1–1.5 μm were synthesized by a facile aqueous method at room temperature. The shell of the synthesized microspheres was composed of aligned nanorods 80–120 nm in diameter and up to 2 μm long. These microspheres exhibit excellent photocatalytic efficiency for the degradation of Rhodamine B under UV irradiation, which was thought to be associated with their hollow structures. The photoluminescence property of the hollow microspheres was also measured.
