Synergistic Enhancement of Electrocatalytic Nitrogen Reductionover Few-Layer MoSe₂-Decorated Ti₃C₂TxMXene

In this work, a few-layered MoSe2on Ti3C2TxMXene (MoSe2/Ti3C2Tx), obtained via a simple one-stephydrothermal synthesis and thermal annealing, is investigated forits potential application as an active electrochemical nitrogenreduction reaction (eNRR) catalyst. The MoSe2/Ti3C2Txcatalystachieved an NH3yield rate of 56.96 mu gh-1mgcat-1at-0.50 VvsRHE and a Faradic efficiency (FE) of 14.08% at-0.35 VvsRHEwith remarkable electrochemical stability. Meanwhile, the densityfunctional theory (DFT) calculations suggest that Mo atoms areactive sites for eNRR, and the distal pathway is the preferred routefor NH3formation on MoSe2/Ti3C2Tx.
