Solvothermal synthesis of ultralong single-crystalline TiO2 nanowires

Abstract: Well-defined single crystalline TiO 2 nanowires with diameters of 20-50 nm mostly and lengths of up to a few millimeters have been successfully synthesized by a simple, low-cost solvothermal process using the mixed solvent aqueous NaOH-ethanol. The as-synthesized nanowires are structurally uniform, of high purity and show perfect crystallinity. The growth mechanism of the nanowires has been investigated by following the growth steps of the samples at various reaction stages. The solvent significantly influence… Show more

“…Preparation of highquality nanocrystals of desired size is a prerequisite for investigating and utilising their size-dependent properties. Various approaches such as chemical precipitation [9], solgel method [10,25,26], hydrothermal method [6,27], 2 Journal of Applied Chemistry microwave-assisted method [28], sonochemical synthesis [29], and solvothermal synthesis [30] have been reported for the synthesis of uniform-sized (or monodisperse) metal oxide and metal oxide nanocomposites with diverse morphologies. Titanium oxide is found in three different crystalline forms: rutile, anatase, and brookite.…”

“…Серед них можна виділити: золь-гель метод [21][22][23], метод осадження з безводного рідинного середовища [24][25][26], гідротермальний [27][28][29], темплатний [30][31][32], сольвотермальний [33][34][35] методи, метод анодного окиснення [36], міцелярний метод [37][38], хімічне осадження з парової фази [39], сонохімічний [40][41][42], та мікрохвильовий [43][44][45] методи. Проте, саме гідро-термальна обробка відкриває широкі можливості для керування морфологією TiO 2 та розміром і ступенем кристалічності його частинок [46].…”

“…Синтез типово проводиться в автоклавах при контролі температури і тиску насичених парів [34,[48][49][50][51][52]. Використовуючи гідротермальний метод синтезу можна отримати різні модифікації ТіО 2 в залежності від природи використаних прекурсорів та рН розчину.…”
