NSR研究论文 | 空气→硝酸→氨：人工固氮的绿色新途径

The commercial HNO3 and NH3 are mostly produced through the Ostwald process and the Haber-Bosch process, respectively. However, high energy demand and enormous greenhouse gas are accompied with these processes. The development of economic and green ways to synthesize HNO3 and NH3 is highly desirable for solving the global energy and environmental crisis. Here, we presented two energy-efficient and environmentally friendly strategies to synthesize HNO3 and NH3 at distributed sources, including the electrocatalytic oxidation of N2 in air to HNO3 and the electrocatalytic reduction of residual NO3− contamination in water to NH3. The isotope labeling studies combined with the theoretical calculation reveal the reaction path of proposed two strategies, confirming the origin of the electrochemical products. Importantly, the electrooxidation generated NO3− ions may also serve as reactants for electroreduction synthesis of NH3 in future. Our work may open avenues for energy-efficient and green production of HNO3 and NH3 at distributed sources.
