摘要：

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 mu g h(-1) mg(cat)(-1) 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.
