Nitrogen fixation by Ru single-atom electrocatalytic reduction
- Abstract:
-
Electrochemical reduction of N2 to NH3 using renewable electricity is a simple and green NH3 production method. Most reported catalytic systems, however, suffer from slow reaction kinetics, low N2 adsorption, and reduction activity. Designing selective and energy-efficient electrocatalysts is highly desirable to enable both high faradic efficiency and NH3 yield rate. Isolating Ru single atoms in N-doped porous carbon significantly promotes N2-to-NH3 conversion, reaching an NH3 formation rate of more than 3.6 mgNH3 h−1mgRu−1. The addition of ZrO2 can effectively suppress the hydrogen evolution reaction, affording a large NH3 faradic efficiency of up to 21% at a low overpotential (0.17 V). This work opens up opportunities for development of single-atom catalysts to facilitate efficient NH3 synthesis.
