Abstract
Well-ordered and vertically aligned BaTiO3 nanotube arrays (BTNTAs) of average diameter 95 nm and wall thickness of 60 nm were prepared by hydrothermal method using titania nanotube arrays as templates. Nanoparticles of SnO2 were also hydrothermally deposited on the surface of BaTiO3 nanotube arrays, to fabricate novel SnO2@BTNTAs heterogeneous nanostructures. Morphology of the SnO2 surface layer on BTNTAs was found to be dependent on the pH employed during hydrothermal synthesis. The visible photocatalytic activity of the SnO2@BTNTAs was evaluated from the degradation of methylene blue (MB). It is found that the SnO2@BTNTAs exhibit enhanced photocatalytic activity under visible-light irradiation when compared to unmodified BTNTAs. Results obtained from the X-ray Photoelectron Spectroscopic and Scanning electron microscopic studies have been combined to establish the influence of defect chemistry and surface morphology on the enhanced visible-light photocatalytic activity of the modified BTNTAs.
