Detergent-free micelle-assisted synthesis of carbon-containing hexagonal CuS nanostructures for efficient supercapacitor electrode materials

Sayed Y. Attia et al.

Summary: This study developed a novel method to control the nanostructure morphology of carbon-containing hexagonal CuS using a single-step solvothermal process. The use of copper II hexafluoroacetylacetonate as the copper source in the presence of two immiscible liquids facilitated the formation of spherical-like shell assembly of hexagonal carbon-containing CuS. This material showed promising potential as an efficient electrode for supercapacitors with enhanced electrochemical properties.
