Synthesis of novel 1–dimensional structure from Mo₆S₈ Chevrel phase of electrode for Mg batteries

Abstract

The Chevrel phase (CP) (Mo6S8), which is used as an electrode material in Mg rechargeable batteries, has a capacity limit owing to ion insertion and trapping. To address this problem, we modify the wire structure of the CP. Mo6S3I6 nanowires, in which iodiene is substituted for Mo6S9 nanowires as infinite CP structures, can be synthesized in various ways. When synthesizing stoichiometrically, an unwanted secondary phase may appear. We solved these problems by reducing the synthesis time. Electrochemical analysis was performed using these nanowires as an active material in Mg batteries.

Halogen-Doped Chevrel Phase Janus Monolayers for Photocatalytic Water Splitting

“…The same strong peaks were observed in the case of NiMo 3 S 4 [ 81 ]; however, no such peaks were found in the case of BaMo 6 S 8 , Cu 1.8 Mo 6 S 8 , Cu 3.2 Mo 6 S 8 , PbMo 6 S 8 , and SnMo 6 S 8 crystals with a Chevrel structure [ 82 ]. In [ 83 ], the Raman spectra of Mo 6 S 3 I 6 nanowires are presented in a wide range of temperatures and the existence of such peaks is shown in the case of samples synthesized at 900 and 1000 °C. At temperatures above 1000 °C, a powder XRD pattern of Mo 6 S 3 I 6 no longer contains lines fitting with MoS 2 and the related bands disappear from the Raman spectra.…”
