“…An efficient strategy for the oxidative cleavage of C=C bonds in olefins using O 2 as the oxidant to form esters with one or multiple carbon atoms less was described using Co SA + NP /NÀ C catalysts (Scheme 1a). [22] The Co SA were the active centers for the Wacker-type oxidation of olefin, and Co NP cleaved the CÀ C bonds in alcohols or ketones to form esters. Quinolines and quinazolinones were efficiently produced on a Fe 3 C NP Fe NP Fe SA /NÀ C catalyst via a cascade coupling process involving oxidative coupling of amines and aldehydes (Scheme 1b).…”

“…Considering the fact that the TOF R1 /TOF R2 ratio is equal to 6.5, an optimization of the density of the two active sites but above all of their relative proportion (Rh SA /Rh NP ratio) should allow to further enhance the catalyst performance. An efficient strategy for the oxidative cleavage of C=C bonds in olefins using O 2 as the oxidant to form esters with one or multiple carbon atoms less was described using Co SA+NP /N−C catalysts (Scheme 1a) [22] . The Co SA were the active centers for the Wacker‐type oxidation of olefin, and Co NP cleaved the C−C bonds in alcohols or ketones to form esters.…”

Catalytic active sites consisting in isolated metal single atoms can be found in enzymatic, homogenous and heterogeneous catalysts. In heterogeneous catalysis, single‐atom catalysts (SACs) may offer high reactivity and selectivity towards some reactions provided their local coordination environment and electronic properties are correctly tuned. These sites generally possess specific properties compared to metal nanoparticles or clusters. Because of the difficulty, inherent in supported catalysis, of preparing catalysts having a high homogeneity of active sites, these two species have had to coexist in many supported catalysts. If the current trend is often limited to comparing the reactivity of these two types of species, we will see in this mini‐review that for few years, work has highlighted a possible synergy between these species to improve catalytic performance. The different types of synergies are discussed, as well as challenges and opportunities for such catalysts in thermal‐, electro‐ and photo‐catalysis.
