research is being conducted on dual-atom catalysts in heterogeneous catalysis, focusing on inter-metal interactions and their effects on various catalytic processes. studies are exploring the synthesis, spatial engineering, and electronic-geometric properties of these catalysts to optimize their performance in reactions such as co2 reduction, oxygen catalysis, and fenton-like catalysis. the research aims to understand and improve the activity and stability of these catalysts, potentially breaking the activity-stability dilemma in electrocatalysis.
