COPPER-BASED SINGLE ATOM ALLOYS FOR HETEROGENEOUS CATALYSIS

Heterogeneous catalysts, as crucial industrial commodities, play an important role in industrial production, especially in energy catalysis. Traditional noble metal catalysts cannot meet the increasing demand. Therefore, the exploration of cost-effective catalysts with high activity and selectivity is important to promote chemical production. Single atom alloy (SAA) catalysts reduce the use of precious metals compared with traditional catalysts. The unique structure of single-atom alloys (SAAs), extremely high atom utilization and high catalytic selectivity make it a prominent position in heterogeneous catalysts. SAAs are widely used in selective hydrogenation/dehydrogenation, carbon dioxide reduction reaction (CO₂RR), hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and nitric oxide reduction reaction (NORR). Here, the applications and research progress of copper-based single atom alloys in various catalytic reactions mentioned above are mainly introduced, and the factors (such as synthesis method, composition content, etc.) affecting the catalytic performance are analyzed by combining with various characterization and testing methods.
