摘要:NH 3 production heavily relies on the traditional Haber-Bosch process, which is not only energy-intensive (1-3% of human's energy consumption) but also carbon-intensive (1.6% of global CO 2 emissions). Electrochemical reduction offers a sustainable and eco-friendly alternative for NH 3 synthesis. Despite tremendous efforts, developing N 2 reduction reaction (NRR) electrocatalysts with high activity and durability remains a great challenge. Here, we firstly report a MoS 2 nanosheet-reduced graphene oxide hybrid (MoS 2 -rGO) as a high-performance catalyst for the NRR. In 0.1 M LiClO 4 , this catalyst attains a high faradaic efficiency of 4.58% and a high NH 3 yield of 24.82 μg h -1 mg cat. -1 at -0.45 V vs. the reversible hydrogen electrode. Notably, such MoS 2 -rGO shows high electrochemical stability during electrolysis and recycling tests. Density functional theory calculations reveal that the potential-determining step of the proton-electron coupling transferring process is ∗NHNH 2 → ∗NH 2 NH 2 , and the following hydrogenation steps are feasible. © 2019 The Royal Society of Chemistry.
