  • Publication number: 20210400956
    Abstract: There is provided a core-shell composite comprising a core which comprises zinc metal and a shell that at least partially encapsulates the core, wherein the shell comprises a salt of the zinc metal as a cation with a sulphur-containing anion. There is also provided a method of forming a core-shell composite comprising the step of heating a mixture of zinc metal particle with elemental sulphur to form the core-shell composite, wherein the zinc metal particle forms the core of the core-shell composite, and wherein the shell of the said core-shell composite at least partially encapsulates the core and comprises a salt of the zinc metal as a cation with a sulphur-containing anion. There is also provided a method of killing or inhibiting the growth of a microbe, comprising the step of subjecting the microbe to the as-disclosed core-shell composite.
