Abstract: The present disclosure provides a Cu1.81S catalyst for synthesizing NH3 and a method for synthesizing NH3 using the same. According to the present disclosure, the Cu1.81S catalyst is provided in order to increase an efficiency of NH3 synthesis. A copper sulfide catalyst and the method for synthesizing NH3 via an electrochemical nitrogen reduction reaction (NRR) using the Cu1.81S catalyst are provided in order to reduce a limiting potential (UL) required for the NRR. In the NRR for the NH3 synthesis, it is provided the copper sulfide catalyst that can be used in any one of two different pathways for the NRR, and the method for synthesizing NH3 with higher activity of the NRR based thereon.
