Template-Free Synthesis of Single Crystal MoO<sub>3</sub> Nanobelts and its Potocatalytic Properties

Uniform 1D MoO 3 nanobelts were synthesized via a facile template-free hydrothermal process using (NH 4 ) 6 Mo 24 ·4H 2 O as raw materials. XRD, FE-SEM, HR-TEM techniques were employed to investigate the phase composition, morphology, and microstructure of as-synthesized samples. The MoO 3 nanobelts have single crystalline orthorhombic phase structure, preferentially grow in [001] direction. The photocatalytic properties were evaluated by the photodegradation of Rhodamine-B under visible light irradiation. The experimental result illustrated that the compound exhibits good photocatalytic performance for degradation of RhB under visible light irradiation.
