- Abstract
Mg2B2O5 nanorods were synthesized in NaCl-KCl-Na2SO4 ternary molten salts using desalinated concentrated seawater. The products were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectrum (FT-IR) and Brunauer–Emmett–Teller (BET). The results showed that Mg2B2O5 nanorods can be obtained at 780°C, the diameter was in the range of 100–150 nm and the length was more than 5 μm. XPS results confirmed that the molar ratio of each atom agreed with the stoichiometric composition of Mg2B2O5. FT-IR showed that the structure of Mg2B2O5 was composed of B(3)-O and B(4)-O units. The BET specific surface area of the sample calculated from N2 isotherms was found to be 9.9408 m²/g, the pore volume was 0.015 cm³/g. The advantage of ternary molten salts method for synthesizing Mg2B2O5 nanorods comparing with single molten salt method was briefly discussed.
