Three kinds of multifunctional hexagonal copper sulfide crystals were successfully synthesized by adjusting the preparation process in this work. The supercapacitor performance of product-based electrodes was studied by CV, GCD and EIS measurements, respectively, from which the product synthesized at 140° was proved to have the most brilliant cycle stability and notable energy density. The impact of pH on photocatalytic decomposition of MO was investigated and a reasonable photocatalytic degradation mechanism was proposed, which suggested that it is at pH 5 that the surface state of the catalyst is most conducive to the photocatalytic reaction. Furthermore, the result of a 5 cycle test at pH 5 indicated that the degradation rate still remained 80.9%. All the experimental results fully indicated that the synthesized CuS nanostructure possessed potential electrical and optical application value.
Pure hexagonal CuS nanoparticles with stable high capacitance and photocatalytic activity were obtained by a mild solvothermal method.
