Glucosan controlled biomineralization of SrCO3 complex nanostructures with superhydrophobicity and adsorption properties

Abstract

Here we report the in vitrobiomineralization of SrCO₃ complex nanostructures obtained using glucosan as the modifier in dimethyl formamide (DMF)–deionized water (DIW) mixed solvents. Rod-, dendrite-, dumbbell-, and sphere-like SrCO₃ nanostructures were achieved by tuning the volume ratios of DMF/DIW, reaction time, and concentrations. The phase, structure, and morphology of the as-obtained products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, and Brunauer–Emmett–Teller (BET) analysis. The possible formation mechanism of SrCO₃ complex nanostructures follows the rod–dumbbell–sphere growth process. The as-synthesized SrCO₃ complex nanostructures show excellent adsorption properties and superhydrophobicity, which may open up a wide range of potential applications in environmental protection.
