Owing　to　the　modifiable　compositions　and　morphologies,　high-efficiency　clean　energy　catalysts　with　complex　functional　structures　attract　wide-ranging　attention.　Herein,　this　report　focuses　on　the　controllably　morphological　MoS2-doped　NiS2/Co3S4　nanocubes　which　are　derived　from　nickel-cobalt　Prussian-blue　analogs.　After　annealing　in　N-2　flow,　MoS2/Ni-CoSx　porous　nanocubes　are　prepared　via　regulating　the　reactant　ratios　(1/2,　1/1　and　2/1)　between　(NH4)(2)MoS4　and　Ni-Co　Prussian-blue　analogs.　In　the　synthesis　progress,　(NH4)(2)MoS4　is　applied　as　a　bifunctional　dopant　source,　which　can　expediently　offer　Mo　and　S　elements　simultaneously.　The　quaternary　porous　MoS2/Ni-CoSx　(1/1)　with　the　reasonable　chemical　composition,　considerable　specific　surface　area　(86.7　m(2)　g(-1))　and　excellent　electrocatalytic　property　can　be　selected　as　the　representative　counter　electrode　catalyst　in　dye-sensitized　solar　cells.　Furthermore,　the　solar　cell　with　MoS2/Ni-CoSx　(1/1)　exhibits　a　higher　power　conversion　efficiency　(9.80%)　than　that　of　Pt　(8.19%)　under　a　standard　irradiation.
