Shape-controlled synthesis of Cu₃₁S₁₆–metal sulfide heteronanostructures via a two-phase approach

Abstract

A series of different-shaped Cu31S16-metal sulfide (ZnS, CdS and CuInS2) heteronanostructures have been synthesized using a simple two-phase approach for the first time. This two-phase approach may shed light on the synthesis of Cu31S16-based heteronanostructures.

In situ tailored strategy to remove capping agents from copper sulfide for building better lithium–sulfur batteries

“…23-0959), where the well-defined Bragg peaks can be assigned to C–Cu 1.93 S products without impurity. 26 As a comparison, the XRD pattern of Cu 1.93 S is shown in Fig. S1a,† which still matches the results for C–Cu 1.93 S. Meanwhile, the XPS results are shown in Fig.…”

“…2f). 26 In a large piece of nanosheet (Fig. 2g), the selected area electron diffraction (SAED) shows a single set of diffraction spots with lattice distribution (Fig.…”

“…2h), suggesting that each nanosheet of C–Cu 1.93 S has a well-crystalized materials nature. 26–28 The corresponding scanning transmission electron microscopy (STEM) image with elemental mapping (EDS) reveals the uniform distribution of Cu and S atoms, which indicates the distribution of the two constituent species over the entire nanosheet (Fig. 2i–l).…”

Construction of High‐Nuclear CuxSy Nanocrystalline Catalyst from High‐Nuclear Copper Cluster

“…have been synthesized,, exhibiting good performance in many areas, such as catalysis, sensors, energy storage, and so on ,. However, much attention has been focused on the low‐nuclear copper sulfide, whereas the properties, as well as the synthetic method toward the high‐nuclear copper sulfide, have received less attention ,. Up to now, only few high‐nuclear copper sulfides, even multi‐nuclear metal chalcogenides, which possess multi‐nuclear structures, abundant active sites and high conductivity, giving more reaction centers and better performance, were synthesized successfully by template method, two‐phase approach, direct metal salt method, decomposition method and so on.…”

However, these methods about syntheses of high‐nuclear metal compounds need extreme operating conditions, which are unamiable and unfriendly to the environment.…”
