“…As indicated previously, an increase in chloride concentration extends the range of stability of abhurite, and in certain solutions it persists to pH 6 (Donaldson et al, 1963). This may have great significance with respect to the natural occurrence of abhurite.…”

“…In contrast to the case of Pb(II), titration of an oxygen-free The extent of this and related phases is uncertain, a fact reflected in the formulation of a number of compounds precipitated from tin(II) solutions, including those containing chloride. Proposed compositions for hydrous tin oxides range from Sn(OH)2, synthesised by an anhydrous organometallic method (Honnick and Zuckerman, 1976), to 5SnO.2H20 (Donaldson and Moser, 1961). Donaldson (1961) has prepared crystalline hydrous tin oxides, which have had the formulae 5SnO.2H20 and, latterly, 3SnO.H20 ascribed to them (Howie and Moser, 1973).…”

The discrepancy in composition (one mol H20 per fifteen mol SnO) is attributable to the presence of chemisorbed water on the surface of the microcrystalline solid (as verified by IR measurements).…”

“…Randall and Murkami (1930) prepared 'SnCI(OH) (s)' under conditions similar to those specified by previous investigators, although the degree of hydration of the phase was uncertain. Donaldson et al (1963) prepared a salt of composition Sn4CI2(OH)6; the synthesis has been reported to yield other substances. Hayek (1933) formulated the compound he obtained as Sn(OH)2.SnCI2, while Randall and Murkami (1930) used the formula SnOHCI.H20 to derive the free energy of formation of the salt.…”

The true formula of abhurite is Sn21Cllr(OH)140 6. A stability constant for the phase has been determined at 298.2 K. For the reaction Sn21CI16(OH)1406 (s) + 26H + (aq) ,~ 21Sn ~+ (aq) + 16CI-(aq) + 20H20 (1), log KH+ (298.2 K) is equal to -39.9 (7). This value is used to assess the relative stability of abhurite in the natural environment and to evaluate its modes of occurrence in relation to other secondary Sn(II) and Sn(IV) species.

“…It increased from 1.3 to 13 with the addition of NaOH solution. It is known that different precipitates including basic chloride and hydrous oxide can be formed during the drop reaction [23]. After the pH value reached 13, a black precipitate was gradually formed with stirring at room temperature.The SEM image of the obtained black precipitates is shown in Figure 2(a).…”

We report a mild template-free hydrothermal route for selective synthesis of SnO 2 hollow microspheres and nano-sheets using SnCl 2 and NaOH as initial materials. By switching the solvent from water to ethanol, the formed SnO 2 nanostructures changed from nano-sheets to hollow microspheres. The obtained nano-sheets were single crystalline in structure. On the basis of the characterization of intermediate products, the formation of SnO 2 hollow microspheres was ascribed to a crystal growth process, while the formation of SnO 2 nano-sheets was ascribed to the oxidation of SnO 2 sheets during the hydrothermal process. Further characterization of the SnO 2 hollow microspheres and nano-sheets by X-ray photoelectron spectroscopy and UV-Vis absorption spectroscopy reveals different optical absorption properties and valence band electronic structures. In addition, the SnO 2 nano-sheets and hollow microspheres exhibit different sensing properties. The present work provides a facile and simple template-free method for the synthesis of nano-structured SnO 2 . SnO 2 , hydrothermal, nanostructure, sensing Citation: Li Y, Guo Y Q, Tan R Q, et al. Selective synthesis of SnO 2 hollow microspheres and nano-sheets via a hydrothermal route.Recently, nano-scale materials have attracted much attention because of their excellent and fascinating properties. Synthesis of nano-materials with controlled morphology, size, chemical composition and crystal structure is of great significance in nano-technological applications. As an n-type wide-bandgap semiconductor, SnO 2 is an important functional material, which has been extensively used in gas sensors and optoelectronic devices [1][2][3][4][5][6][7]. In recent years, SnO 2 nanostructures with various geometrical morphologies have been reported, including hollow structures, nano-belt/ wire/tubes/rods, nano-diskettes, nano-sheets, and nano-particles [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Various preparation methods have been explored, including hydrothermal methods, thermal evaporation, sol-gel methods, co-precipitation, and direct oxidation [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. The hydrothermal processes, especially starting from aqueous solutions, are the most widely investigated.To control the morphology of SnO 2 , template-assisted methods were usually adopted in previous studies. The use of templates has some disadvantages such as high cost and tedious synthetic procedures, which may limit their large-scale applications. However, experimental trials for the SnO 2 preparation by template-free routes are inadequate. The control of morphology using template-free hydrothermal routes for synthesis of SnO 2 nanostructure is still challenging. In this paper, we demonstrate a novel template-free (or surfactant-free) hydrothermal process for the selective synthesis of SnO 2 hollow microspheres and nano-sheets by simply changing the solvent. Their optical and electronic structural properties are also presented.

Three tin oxide halides, Sn 7 O 4 Cl 6 , Sn 7 O 4 Br 6 , and Sn 4 OI 6 , were synthesized by solid-state reactions of SnO and SnX 2 (X=Cl, Br, I) at 300°C. Crystal structures were solved and refined from single crystal X-ray diffraction data, revealing the presence of cubane-like [Sn 4 O 4 ] units in the structures of Sn 7 O 4 Cl 6 and Sn 7 O 4 Br 6. The electronic structure of Sn 7 O 4 Cl 6 was analyzed by DFT band structure calculations and the electron localization function (ELF).
