Cooperativity between atoms in supported Single-Atom Catalysts and metal clusters

[EN] Highlights ¿ Cooperativity and electron-transfer between metals and supports are key phenomena to understand the performance of SACs and small metal clusters. ¿ Single-atom catalysts often require the support to actively participate in the reaction to achieve optimal catalytic performance. ¿ Small amounts of metal clusters could be contributing to the catalysis by SACs. ¿ SACs and metal clusters often show unique opportunities in terms of catalytic selectivity. ¿ The high mobility of supported clusters and SACs makes operando work crucial.
