Ionic Liquids Tailoring Trigonal Selenium Microrods under Solvothermal Conditions.

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.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.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.
