Inorganic and organic templates‐assisted solvothermal synthesis of trigonal selenium microrods

A facile and environment‐friendly solvothermal method has been developed for the controlled growth of nano‐ and micro‐structured trigonal selenium (t‐Se) by using green templates. And, the morphology of trigonal selenium can be tuned by using different kinds of templates. The as‐obtained products were characterized by X‐ray powder diffraction (XRD) and scanning electron microscope (SEM). Furthermore, the formation mechanism of trigonal selenium nano‐ and microcrystals was rationally suggested. This method will open a new avenue to synthesize other functional inorganic nano‐ and microcrystals. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
