SrNb2O6nanotubes with enhanced photocatalytic activity

Abstract

SrNb2O6 having a rhombic nanotubular structure with a diameter of 300 nm, average length of 3 μm and wall thickness of 50 nm was synthesized via a facile hydrothermal route. The prepared powders were characterized using X-ray diffraction, field-emission electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM) and Raman spectroscopy. Compared to the same material prepared by the solid-state reaction method, the rhombic nanotubes of SrNb2O6 exhibited enhanced photocatalytic activity for the production of H2 from pure water, which was mainly attributed to their higher surface area. Moreover, the increased optical absorption properties resulting from the variation of the crystal structure also contributed to their higher photocatalytic activity.
