Abstract
Disclosed herein are methods of producing metal sulfide materials, including cathode materials. In some embodiments, the metal sulfide material comprises a secondary cluster of metal sulfide nanoparticles surrounded by a carbon layer. The carbon layer may be created by carbonizing one or more polymer layers disposed about the secondary cluster. The carbonized layer may aid in optimizing performance of the cathode material. Also disclosed herein are methods, processes, devices, and systems for removing hydrogen sulfide from a waste stream. In some embodiments, the waste stream containing hydrogen sulfide is a gas. The waste stream can be combined with a solvent containing a metal-catalyst complex, and the reaction of hydrogen sulfide with the metal results in production of a hydrogen gas and a solid comprising metal sulfide.
