摘要
Synthesis of ammonia by electrochemical nitrogen reduction reaction (NRR) is a promising alternative to the Haber‐Bosch process. However, it is commonly obstructed by the high activation energy. Here, we report the design and synthesis of an Al‐Al bonded dual atomic catalyst stabilized within an amorphous nitrogen‐doped porous carbon matrix (Al2NC) with high NRR performance. The dual atomic Al2‐sites act synergistically to catalyze the complex multiple steps of NRR through adsorption and activation, enhancing the proton‐coupled electron transfer. This Al2NC catalyst exhibits a high Faradic efficiency of 16.56±0.3% with a yield rate of 29.22±1.2 µg.h‐1.mgcat‐1. The dual atomic Al2NC catalyst shows long‐term repeatable, and stable NRR performance. This work presents an insight into the identification of synergistic dual atomic catalytic site and mechanistic pathway for the electrochemical conversion of N2 to NH3.
