High-Performance Electrocatalytic Conversion of N₂ to NH₃ Using 1T-MoS₂ Anchored on Ti₃C₂ MXene under Ambient...

Herein, 1T-MoS₂ nanospots assembled on conductive Ti₃C₂ MXene (1T-MoS₂@Ti₃C₂) are first developed to regard as efficient electrocatalytic nitrogen fixation catalysts with high selectivity. The 1T-MoS₂@Ti₃C₂ composite exhibits outstanding NRR activity with a faradic efficiency (FE) of 10.94% and a NH₃ yield rate of 30.33 μg h^-1 mg^-1_cat. at -0.3 V versus RHE. Notably, the 1T-MoS₂@Ti₃C₂ composite displays excellent stability and durability during the recycling test. The outstanding NRR catalytic activity is primarily attributed to the synergy effect between 1T-MoS₂ and Ti₃C₂ MXene. In addition, the isotopic experiment confirms the synthesized NH₃ deriving from the conversion of the supplied nitrogen.
