▎ 摘　　要

NOVELTY - Molybdenum sulfide-tin sulfide/poly 1-vinyl-3-propane sulfonyl imidazole bromide/polypyrrole/graphene oxide nano material material is prepared by polymerizing pyrrole on graphene oxide nanosheets, adding polypyrrole/graphene oxide nanosheets to N,N-dimethylformamide, ultrasonically dispersing, then adding chloropropylene and potassium hydroxide, stirring and reacting in oil bath at 60degrees Celsius for 24 hours, centrifuging, washing, vacuum drying, adding polypyrrole/graphene oxide-propylene nanosheets to absolute ethanol, ultrasonically dispersing, adding 1-vinyl-3-propane sulfonyl imidazole bromide and initiator, and transferring to 80degrees Celsius oil bath, refluxing under nitrogen protection for 6 hours, centrifuging, washing, and vacuum drying, dispersing poly 1-vinyl-3-propane sulfonyl imidazole bromide/polypyrrole/graphene oxide nanosheets in water, then adding ammonium-molybdenum-oxide tetrahydrate, tin chloride pentahydrate and thioacetamide, stirring evenly, and hydrothermally reacting. USE - Molybdenum sulfide-tin sulfide/poly 1-vinyl-3-propane sulfonyl imidazole bromide/polypyrrole/graphene oxide nano material used for forming NRR electrocatalytic modified electrode for electrocatalytic nitrogen reduction (all claimed). ADVANTAGE - The molybdenum sulfide-tin sulfide/poly 1-vinyl-3-propane sulfonyl imidazole bromide/polypyrrole/graphene oxide nano material has low price and high catalytic performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of a nitrogen-reduction rate (NRR) electrocatalytic modified electrode in electrocatalytic nitrogen reduction.
