Synthesis of nanosized NaTaO3 in low temperature and its photocatalytic performance

A simple synthetic route in mild condition to obtain nanosized NaTaO3 powder with cubic morphology is reported in which the compound was hydrothermally prepared at 120 degreesC for 12 h. The cubic crystalline structure of this nanosized NaTaO3 product was ensured by using XRD and TEM. The band gap of the nanosized NaTaO3 was 3.96eV based on UV spectrum. The hydrothermal process probably follows the dissolution-precipitation mechanism. Also this NaTaO3 powder showed high photoreactivity under UV light in gas phase and liquid phase photoreactions.
