Size- and Surface-Determined Transformations: From Ultrathin InOOH Nanowires to Uniform c-In<sub>2</sub>O<sub>3</sub> Nanocubes and rh-In<sub>2</sub>O<sub>3</sub> Nanowires Xiangxing Xu Xun Wang 10.1021/ic802449w.s001 https://acs.figshare.com/articles/journal_contribution/Size_and_Surface_Determined_Transformations_From_Ultrathin_InOOH_Nanowires_to_Uniform_c_In_sub_2_sub_O_sub_3_sub_Nanocubes_and_rh_In_sub_2_sub_O_sub_3_sub_Nanowires/2862817 Ultrathin InOOH nanowires with a diameter of ∼2 nm and a length up to ∼200 nm have been synthesized by a hydrolysis reaction in a solution system. Their transformations to c-In<sub>2</sub>O<sub>3</sub> nanocrystals and rh-In<sub>2</sub>O<sub>3</sub> nanowires have been investigated. A dissolution−recrystallization (in solution) or size-related decomposition−recrystallization (in air) mechanism is indicated for the former transformation; the size- and surface-determined transformation is proposed for the latter. These results will help to understand and control the phase stability and transformation concerning the nanodimension and surface restrictions, especially for ultrathin nanowires. 2009-04-20 00:00:00 Ultrathin InOOH Nanowires ultrathin nanowires hydrolysis reaction transformation solution system surface restrictions phase stability 2O nm
