Abstract

Abstract : A controllable solvothermal method was used to fabricate FeSe2 alloys with special microtube and nanosheet morphology. Abstract : Iron diselenium (FeSe2 ) with rational design and tailored synthesis is a promising transition metal chalcogenide because of its suitable optical and electronic properties. Despite these prospects, controllable synthesis of FeSe2 with a special hierarchical heterostructure has hardly been paid attention to previously. Here, we report a successful synthesis of FeSe2 microtubes in a system of water glycol mixture using a sacrificial self-template method. This method leads to the formation of a FeSe2 microtube embedded with nanooctahedra in the remaining Se template, which can be regarded as a special hetero-junction morphology. Moreover, a growth mechanism of the FeSe2 microtube was discussed. This unique morphology and facile synthesis might facilitate the study of transition metal chalcogenides.
