Microwave-Hydrothermal Synthesis of SnO(2)-CNTs Hybrid Nanocomposites with Visible Light Photocatalytic Activity

SnO(2) nanoparticles coated on carbon nanotubes (CNTs) were prepared via a simple microwave-hydrothermal route. The as-obtained SnO(2)-CNTs composites were characterized using X-ray powder diffraction, Raman spectroscopy, and transmission electron microscopy. The photocatalytic activity of as-prepared SnO(2)-CNTs for degradation of Rhodamine B under visible light irradiation was investigated. The results show that SnO(2)-CNTs nanocomposites have a higher photocatalytic activity than pure SnO(2) due to the rapid transferring of electrons and the effective separation of holes and electrons on SnO(2)-CNTs.
