Ionic Liquids Tailoring Trigonal Selenium Microrods under Solvothermal Conditions

Abstract

 An ionic liquids(ILs)-assisted solvothermal synthesis route has been proposed to preparing high-purity trigonal selenium (t-Se) microrods using sodium selenite and hydrazine hydrate as starting materials. The asobtained samples are characterized by the X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. By choosing ionic liquids employed in the synthesis of t-Se, the aspect ratio of the as-synthesized Se microrods could be tailored. Furthermore, possible formation mechanism of t-Se microrods was rationally proposed. BF4- anions were found to play crucial roles in the formation of t-Se microrods, and the chain length of ILs had important effect on the determining the aspect of t-Se microstructures. This method may provide a new idea for the direct growth of inorganic nanomaterials with various morphologies by choosing anions and cations of ionic liquids.
