Electrical And Photocatalytic Properties Of Na_2ti_6o_(13) Nanobelts Prepared By Molten Salt Synthesis

摘要

Single-crystalline Na_2Ti_6O_(13) nanobelts were prepared on large-scale by molten salt synthesis at 825 ℃ for 3 h. The obtained nanobelts have typical width of less than 200 nm and thickness of 10-30 nm, and length up to 10 μm. The growth direction of the nanobelts was determined to be along [010]. Electrical transport property of an individual nanobelt was measured at room temperature and ambient atmosphere, and results showed that the nanobelts are semiconductor. Na_2Ti_6O_(13) nanobelts exhibited good photocatalytic efficiency for the degradation of RhB under UV irradiation.
