METAL-DOPED MOLYBDENUM SULFIDE POWDER AND PRODUCTION METHOD THEREFOR

A metal-doped molybdenum sulfide powder according to the present invention contains a doping metal in Groups 3 to 13 and molybdenum disulfide having a 3R crystal structure. A first aspect of a method for producing a metal-doped molybdenum sulfide powder according to the present invention includes dry-mixing a powder containing a molybdenum trioxide powder made of an aggregate of primary particles containing molybdenum trioxide having an α crystal structure or a β crystal structure, a sulfur source, and a salt of a metal in Groups 3 to 13, and heating the powder at a temperature of 200°C to 1,000°C. A second aspect of the method includes removing, from a mixture obtained by blending a molybdenum trioxide powder made of an aggregate of primary particles containing molybdenum trioxide having an α crystal structure or a β crystal structure, a salt of a metal in Groups 3 to 13, and a dispersion medium, the dispersion medium to obtain a solid, and heating the solid at a temperature of 200°C to 1,000°C in the presence of a sulfur source.
