摘要：

Ti-O based nanomaterials were successfully synthesized via an alkali-assisted hydrothermal process, and were characterized by transmission electron microscopy (TEM) and scanning electron microscope (SEM). Using commercial anatase TiO2 powders as precursor, 10 mol/L NaOH aqueous solution as solvent, when the hydrothermal reaction was conducted at 180℃ in a Teflon-lined autoclave for 48 h, Ti-O based nanobelts could be obtained. The characterization indicated that the nanobelts with typical widths of 50 to 200 nm, thicknesses of 20 to 50 nm, were up to dozens of micrometer in length. When the hydrothermal treatment temperature was 120℃, Ti-O nanotubes could be obtained, whose lengths and external diameters ranged from 200 to 500 nm and 20 to 50 nm, respectively. The experiment inferred that when the crystalline size of the precursor is relatively small, it is easy to form fine or narrow nanobelts or nanowires, when the precursor has a relatively large particle size, uniform nanobelts can be obtained. © 2016, Materials Review Magazine.
