摘要：

We report on the first general preparation of one dimensional (1D) MTiO3 (M = Ba, Sr, Pb) nanostrips by a surfactant-free approach in nonaqueous molten salt media. The as-synthesized MTiO3 nanostrips were characterized by electron microscopic techniques, X-ray diffraction (XRD), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The MTiO3 nanostrips are characterised by a width of 50-200 nm, a thickness of 20-50 nm, and a length of several to tens of micrometers. The growth processes of the MTiO3 nanostrips have been studied and discussed.
