Ultrathin MoS2 Nanosheets for Electrocatalytic N2-To-NH3 Fixation Under Ambient Conditions

Electrochemical N 2 reduction reaction (NRR) provides a quite potential method for ammonia (NH 3 ) synthesis under ambient conditions, while it requires efficient and durable catalysts. In this communication, we report an ultrathin nanosheets MoS 2 that acts as electrocatalyst for NRR, which assumed excellent selectivity. In 0.1 M Na 2 SO 4 with N 2 -saturation under ambient conditions, this electrocatalyst at -0.6 V vs. reversible hydrogen electrode (RHE) exhibited a large NH 3 yield of 41.66 μg h -1 mg -1 cat . and a Faradaic efficiency (FE) of 1.10%. Furthermore, the electrochemical stability is also exhibiting excellent.
