Table 1. Advantages and Disadvantages of SACs.

advantages disadvantages
▶ Highly tunable binding energies to reacting species allowing to adjust catalytic activity to the maximum of the Brønsted–Evans–Polanyi relation.33,34 ▶ Often high surface free energy
▶ Maximum dispersion, theoretically high catalytic efficiency (unless catalysts with small clusters and monolayers, which also offer 100% dispersion, are considered). ▶ High risk of agglomeration under harsh reaction conditions or pretreatments.
▶ Emerging applications in wide range of materials such as thermal, electro, photocatalysts, where knowledge driven approach between molecular and solid catalysts is key for the findings. ▶ Synthesis often results in nonuniform mixture of different species, challenging to adequately identify active species and characterize with readily available spectroscopic techniques.
▶ Potential for selective reaction pathway, minimization of side reactions. ▶ Limited to low metal concentration, high mass of catalyst, higher risk of mass-transfer limitations in comparison to clusters and nanoparticle catalysts.
