Preparation of CNT@Mo-Ag bimetallic sulfide with a mass ratio of 2:1 using planetary ball milling: 0.5 g of Mo-Ag bimetallic sulfide prepared at a hydrothermal temperature of 200 ℃ and 1 g of CNT were placed in an agate ball milling jar. The mass ratio of the ball material was 120:1, and the planetary ball mill was operated at a speed of 400 r/min for 4 hours before extraction.

Preparation of CNT@Mo-Ag bimetallic sulfide with a mass ratio of 20:1 using planetary ball milling: 0.05 g of Mo-Ag bimetallic sulfide prepared at a hydrothermal temperature of 200 ℃ and 1 g of CNT were placed in an agate ball milling jar. The mass ratio of the ball material was 120:1, and the planetary ball mill was operated at a speed of 400 r/min for 4 hours before extraction.

Preparation of physically mixed CNT/Mo-Ag bimetallic sulfide with a mass ratio of 2:1: In the preparation of the working electrode, 3.3 mg of Mo-Ag bimetallic sulfide prepared at a hydrothermal temperature of 200 ℃ and 6.7 mg of CNT were chosen as catalysts. The other steps remained the same.

Preparation of physically mixed CNT/Mo-Ag bimetallic sulfide with a mass ratio of 20:1: In the preparation of the working electrode, 0.5 mg of Mo-Ag bimetallic sulfide prepared at a hydrothermal temperature of 200 ℃ and 9.5 mg of CNT were chosen as catalysts. The other steps remained the same
