1. A method of manufacturing a porous core-shell catalyst structure, the method comprising:
preparing a bulk cobalt oxide having a first oxygen content;
providing a first reaction gas containing nitrogen to the bulk cobalt oxide to produce an intermediate product containing a porous cobalt oxide, wherein the intermediate product has a second oxygen content that is lower than the first oxygen content; and
providing a second reaction gas containing sulfur to the intermediate product to produce a porous core-shell catalyst structure including a core formed of the porous cobalt oxide and a shell formed of cobalt sulfide.
