The invention discloses a method for preparing a ternary sulfide catalyst by utilizing a waste battery and application of the ternary sulfide catalyst. The method comprises the following steps: S1, separating and collecting a positive electrode material; s2, preparing an electro-deposition leaching solution; s3, a layered NiCoMn (OH) x / NF precursor is prepared through primary electro-deposition; s4, a NiCoMnS < x > / NF catalyst is prepared through secondary electro-deposition; the catalyst is applied to an electro-catalysis hydrogen evolution reaction and a sulfur ion oxidation reaction. The method is simple in process, controllable in cost and free of toxic gas generation, and the catalyst is excellent in performance, so that the catalyst shows extremely high applicability and popularization value in industrial production.

The invention discloses a cobalt-doped nickel molybdenum sulfide electrode material, a preparation method of the cobalt-doped nickel molybdenum sulfide electrode material and application of the cobalt-doped nickel molybdenum sulfide electrode material in electro-catalytic synthesis of 3, 4-dihydroisoquinoline. A simple hydrothermal method is adopted to directly grow a cobalt-doped nickel molybdenum oxide precursor on a foamed nickel substrate in situ, and then the cobalt-doped nickel molybdenum oxide precursor is subjected to vulcanization treatment to prepare the Co-NiMo-S / NF self-supporting electrode material. The electrode can efficiently catalyze tetrahydroisoquinoline to be selectively oxidized into 3, 4-dihydroisoquinoline under the normal-temperature and alkaline conditions, the conversion rate is larger than or equal to 85%, the selectivity is close to 100%, and meanwhile generation of deep oxidation product isoquinoline is effectively inhibited; the ternary sulfide electrode is applied to the reaction system for the first time, the catalyst cost is low, the preparation process is simple, the reaction conditions are mild, and the method has good industrial application prospects.
