Retracted Article: Fabrication of hollow CoS1.097 prisms toward supercapactior performance

Abstract

The controlled synthesis of a variety of microstructures is valuable for understanding the relationship between morphology and properties and exploring potential applications. In this paper, hollow CoS1.097 prisms were prepared by prismatic Co-precursors using thioacetamide (TAA) as a sulfidation treatment reagent. A plausible mechanism was proposed for the formation of the hollow prism structure. S2− comes from TAA to displace the anions in Co-precursors by adjusting temperature and pressure. The original prism morphology of the Co-precursor was maintained and a hollow prismatic structure was formed by an anion exchanging process. Interestingly, the composition of samples after sulfidation treatment can be controlled by changing the diffusion to obtain Co3O4/CoS1.097 and CoS1.097 materials. As electrode materials for supercapacitors, hollow CoS1.097 prisms revealed ideal electrochemical performance.
