Selective synthesis and magnetic properties of FeSe2 and FeTe2 nanocrystallites obtained through a hydrothermal co-reduction route

Abstract A hydrothermal co-reduction method has been developed to fabricate ferroselite (FeSe 2 ) nanorods and frohbergite (FeTe 2 ) nanocrystallites using N 2 H 4 ·H 2 O as the reductant. The experimental results indicate that the concentration of N 2 H 4 ·H 2 O and the proportion of the starting materials play important roles in obtaining pure FeSe 2 and FeTe 2 nanocrystallites. Meanwhile, the magnetic properties of the as-obtained FeSe 2 and FeTe 2 nanocrystallites are measured at room temperature.
