Abstract

We report the solvothermal synthesis of tubular BaTiO₃ nanoparticle assembly in ethanol/water mixed solvent system using Na ₂Ti₃O₇ nanowires as template. The obtained tubular BaTiO₃ nanoparticle assembly, with a straight interior shell, is constructed by nanoparticles with diameters of 150-400 nm on the outer surface. The tubular BaTiO₃ nanoparticle assembly retains the one-dimensional characteristic inherited from the precursor Na ₂Ti₃O₇ nanowires during solvothermal process. The formation mechanism of the hollow interior of tubular BaTiO₃ nanoparticle assembly is deriving from nanoscale Kirkendall effect, and the growth of nanoparticles on the outer surface with different sizes is controlled by the Ostwald ripening process, resulting in larger meaning outer diameter.
