SINGLE-ATOM CATALYSTS

, 2022
Nanocatalysts have attracted great attention and played an important role in various chemical reactions due to their nanostructure properties and good activities. However, nanocatalysts still have limitations such as relatively low atom utilization, multiple active centers, and the high cost of noble metal-based nanocatalysts.

Unraveling CO adsorption on model single-atom catalysts [PDF]

Science, 2021
Modeling single-atom reactivity Noble metals often perform best for demanding reactions such as oxygen reduction, an effect often explained by the position of their d-band. One way to minimize the cost of noble metals is to disperse them as single atoms. To model the reactivity of supported single atoms, Hulva et al.
