Direct hydrothermal synthesis of single-crystalline triangular Fe3O4 nanoprisms

Abstract

Single-crystalline Fe3O4 triangular nanoprisms (TNPs) were fabricated by a facile hydrothermal route in the presence of 1,3-propanediamine (PDA). It was found that the EG to PDA volume ratio played an important role in the formation of the TNP structures and greatly affected the morphology of the magnetites.
