Engineering Local Coordination and Electronic Structures of Dual-Atom Catalysts

Area of Science:

• Materials Science
• Catalysis
• Sustainable Chemistry

Background:

• Dual-atom catalysts (DACs) are atomically precise catalysts with isolated metal pairs on supports.
• DACs offer advantages over single-atom catalysts by overcoming limitations like restricted active sites and spatial constraints.
• Significant interest exists in DACs for sustainable energy and chemical production.

Purpose of the Study:

• To review recent progress and challenges in heterogeneous dual-atom catalysts.
• To explore the relationship between local atomic environments and catalytic behavior in DACs.
• To highlight the importance of optimizing the entire catalytic ensemble for efficient performance.

Main Methods:

• Discussion of local modulation of coordination and electronic structures in DACs.
• Case studies demonstrating the impact of atomic structure on catalytic performance.
• Analysis of synthesis, characterization, and application challenges.

Main Results:

• Local atomic environments significantly influence catalytic performance in DACs.
• Optimizing the entire catalytic ensemble is crucial for efficient, selective, and stable reactions.
• Understanding the structure-activity relationship is essential for DAC development.

Conclusions:

• DACs show great potential for sustainable energy and chemical production.
• Further research is needed to fully understand and exploit DACs.
• Addressing challenges in synthesis, characterization, and application is key to unlocking DAC potential.
