The　yolk-shell　structure　electrocatalysts　formed　by　polymetallic　sulfides　hold　great　promise　in　a　variety　of　energy　conversion/storage　fields.　Herein,　the　nitrogen/sulfur　codoped　porous　carbon　encapsulated　Co3S4@NiS/Cu2S　nanopolyhedrons　(NSC-Co3S4@NiS/Cu2S)　with　hierarchical　yolk-shell　structures　were　successfully　designed　and　synthesized　by　a　facile　one-step　high-temperature　degradation　of　zeolite　imidazolate　framework-67　(ZIF-67)　wrapped　with　metal-doped　trithiocyanuric　acid　(TCA-M).　Trithiocyanuric　acid　played　a　dual　role,　not　only　providing　nitrogen,　sulfur,　and　carbon　sources,　but　also　playing　a　role　in　the　sulfurization　of　metal　elements.　It　is　worth　noting　that,　due　to　the　higher　specific　surface　area,　unique　morphology,　multi-element　synergies,　and　more　favorable　chemical　composition,　the　synthesized　samples　possessed　outstanding　bifunctional　electro-catalytic　performance　for　dye-sensitized　solar　cells　(DSSCs)　and　hydrogen　evolution　reactions　(HERs).　Experi-mental　results　showed　that　NSC-Co3S4@NiS/Cu2S　electrode　has　a　high　photoelectric　conversion　efficiency　(9.57%)　in　DSSCs.　In　addition,　NSC-Co3S4@NiS/Cu2S　electrode　also　showed　a　lower　initial　overpotential　(65.1　mV)　and　Tafel　slope　(49.7　mV　dec-1)　in　the　alkaline　HERs　test.　The　present　approach　has　proposed　a　new　syn-thetic　idea　of　hierarchical　yolk-shell　metal　sulfide　in　different　new　energy　catalysis　fields.
