[0033] Example 1
[0034] Ammonium molybdate ((NH 4 ) 6 Mo 7 O 24 .24H 2 O) 13.6g and a concentration of 22% ammonium sulfide ((NH 4 ) 2 S) 120ml of the solution was reacted for one hour at 60℃ with stirring, and 50ml of concentrated acetic acid (CH 3 COOH) and ion-free water to completely dissolve part of the precipitate and prepare a 1.0M ammonium thiomolybdate solution. Weigh nickel acetate (Ni(CH 3 COO) 2 .4H 2 O)4.7g, manganese acetate (Mn(CH 3 COO) 2 .4H 2 O) 1.7 g are dissolved together in 150 ml of deionized water, and the solution is dissolved with ammonium thiomolybdate. The solution and 300ml of 30% acetic acid solution were reacted at 60°C with stirring to form a black precipitate. Washing, filtering, and vacuum drying at 120°C to obtain a molybdenum-based precipitate. Weigh 1.7g of ferrous sulfide and the same quality of citric acid and mix thoroughly, raise to 450℃ under the protection of nitrogen, roast at a constant temperature for 2 hours, cool to room temperature...

[0035] Example 2
[0036] Ammonium molybdate ((NH 4 ) 6 Mo 7 O 24 .24H 2 O) 13.6g and a concentration of 22% ammonium sulfide ((NH 4 ) 2 S) 120ml of the solution was reacted for one hour at 60℃ with stirring, and 50ml of concentrated acetic acid (CH 3 COOH) and ion-free water to completely dissolve part of the precipitate and prepare a 0.5M ammonium thiomolybdate solution. Weigh nickel acetate (Ni(CH 3 COO) 2 .4H 2 O)6.4g, manganese acetate (Mn(CH 3 COO) 2 .4H 2 O) 3.4 g are dissolved together in 150 ml of deionized water, and this solution reacts with ammonium thiomolybdate solution and 300 ml of 30% acetic acid solution at 60° C. with stirring to form a black precipitate. Washing, filtering, and vacuum drying at 120°C to obtain a molybdenum-based precipitate. Weigh 1.15g of ferrous sulfide and the same quality of citric acid and mix thoroughly, raise to 450℃ under the protection of nitrogen, roast at a constant temperature for 2 hours, cool to room temperature, mix well with 3.5g...

[0037] Example 3
[0038] Ammonium molybdate ((NH 4 ) 6 Mo 7 O 24 .24H 2 O) 13.6g and a concentration of 22% ammonium sulfide ((NH 4 ) 2 S) 120ml of the solution was reacted for one hour at 60℃ with stirring, and 50ml of concentrated acetic acid (CH 3 COOH) and ion-free water to completely dissolve part of the precipitate and prepare a 0.8M ammonium thiomolybdate solution. Weigh nickel acetate (Ni(CH 3 COO) 2 .4H 2 O) 3.2g, manganese acetate (Mn(CH 3 COO) 2 .4H 2 O) 1.7 g are dissolved together in 150 ml of deionized water, and the solution is reacted with ammonium thiomolybdate solution and 300 ml of 30% acetic acid solution at 60° C. with stirring to form a black precipitate. Washing, filtering, and vacuum drying at 120°C to obtain a molybdenum-based precipitate. Weigh 2.3g of ferrous sulfide and citric acid of the same quality, fully mix, raise to 450℃ under the protection of nitrogen, roast at constant temperature for 2 hours, cool to room temperature, fully mix with 3.5g of p...
