Embodiment 1
[0023] The first step: the carbon cloth (3*3cm 2 ) in acetone, ethanol, and water for 10 minutes in sequence, and set aside;
[0024] The second step: mix ammonium molybdate and thiourea in water in proportion, wherein the molar ratio of ammonium molybdate and thiourea is 1:5, and the volume of water is 35mL and stirred until completely dissolved to obtain a uniform solution;
[0025] Step 3: Transfer the uniformly stirred solution to a reaction kettle with a stainless steel substrate and put it into an ultrasonically passed carbon cloth, and place the reaction kettle in a blast drying oven at 180°C for 12 hours; after cooling down to room temperature, put The carbon cloth was taken out and rinsed with ethanol and water in turn, and dried to obtain MoS 2 nanosheet catalysts.
Embodiment 2
[0027] The first step: the carbon cloth (3*3cm 2 ) in acetone, ethanol, and water for 10 minutes in sequence, and set aside;
[0028] The second step: mix ammonium molybdate and thiourea in water in proportion, wherein the molar ratio of ammonium molybdate and thiourea is 1:5, and the volume of water is 35mL and stirred until completely dissolved to obtain a uniform solution;
[0029] Step 3: Transfer the uniformly stirred solution to a reaction kettle with a stainless steel substrate and put it into an ultrasonically passed carbon cloth, and place the reaction kettle in a blast drying oven at 180°C for 12 hours; after cooling down to room temperature, put The carbon cloth was taken out and rinsed with ethanol and water in turn, and dried to obtain MoS 2 nanosheet catalysts.
[0030] In the fourth step, 10mL of ammonia water is placed in the reactor, and the MoS 2 The nanosheets are placed above the ammonia water without contact with the ammonia water, and the reaction kett...
