Cu5.5FeS6.5 nanotubes—a new kind of ternary sulfide nanotube

Abstract

A new kind of ternary sulfide nanotubes, Cu 5.5 FeS 6.5 nanotubes, was synthesized in autoclaves at 195 C, and it was found that armchair, zigzag and complex arrangements exist in the nanotubes.

Solvothermal Synthesis of Non‐Oxide Nanomaterials

“…Some other ternary chalcogenides have also been prepared by the solvothermal method, such as Cu 5:5 FeS 6:5 nanotubes [126], AgBiS 2 nanowhiskers [127], Cu 2 SnS 3 [128], Cu 2 SnSe 4 [129], CuSbS 2 and Ag 3 SbS 3 [130] nanoparticles.…”

A Two‐Step Route to Self‐Assembly of CdS Nanotubes via Electrodeposition and Dissolution

“…For example, Remskar et al [15] reported the self-assembly of subnanometerdiameter single-wall MoS 2 nanotubes, and rare-earth oxide [ nanotubes have been formed from dodecylsulfate assemblies. [16] Similarly, Te, [17] NbS 2 , [18,19] WS 2 , [20] Cu 5.5 FeS 6.5 , [21] and ReS 2 [22] nanotubes have also been synthesized by selfor induced-assembly. Motivated by these reports, we now report a two-step synthesis of CdS nanotubes based on a self-assembly approach.…”
