Dual single-atom catalysts (DSACs) offer a promising, low-energy approach for ammonia production via electrocatalytic N2 reduction reaction (ENRR). These catalysts enhance efficiency and ammonia yield compared to single-atom catalysts.
Area of Science:
- Materials Science
- Electrochemistry
- Catalysis
Background:
- Ammonia is crucial for fertilizers and fuels, but the Haber-Bosch process is energy-intensive and polluting.
- Electrocatalytic N2 reduction reaction (ENRR) under mild conditions offers a sustainable alternative.
- Single-atom catalysts (SACs) show potential but suffer from low efficiency and ammonia yield.
Purpose of the Study:
- To review recent advancements in dual single-atom catalysts (DSACs) for electrochemical N2 reduction reaction (ENRR).
- To explore the design, mechanisms, and performance of DSACs for sustainable ammonia synthesis.
Main Methods:
- Comprehensive review of theoretical calculations and experimental studies on DSACs for ENRR.
- Analysis of DSACs' variety, coordination, support materials, and N2 adsorption mechanisms.
- Examination of NRR activity and electrochemical cell configurations.
Main Results:
- DSACs demonstrate enhanced N2 activation and synergistic effects between adjacent atoms.
- DSACs show improved faradaic efficiency and ammonia formation yield compared to SACs.
- Diverse DSAC designs offer tunable electronic structures and active sites for optimized ENRR.
Conclusions:
- DSACs represent a significant breakthrough in developing efficient and sustainable electrocatalytic ammonia synthesis.
- Further research into DSACs' mechanisms and rational design is crucial for practical applications.
- DSACs hold great promise for revolutionizing ammonia production with reduced environmental impact.
