Bridging homogeneous and heterogeneous catalysis by heterogeneous single-metal-site catalysts

Carbon‐Rich Nonprecious Metal Single Atom Electrocatalysts for CO2 Reduction and Hydrogen Evolution

“…I) High metal utilization: The SACs featuring a broad distribution structure reduce the metal size from nanoclusters or nanoparticles (NPs) to isolate atoms, which lessens the necessary metal amounts, consequently minimizing material cost. The broad distribution structure crucially impacts the catalytic performance, opening a new frontier in breaking the traditional linear scaling relationship of homogeneous and heterogeneous catalysts . II) Strong interaction between atoms and supports: the covalent bonds between single metal atoms and supports could result in accurate control over the structure, making it easier to understand the possible catalytic sites.…”

Single-Atom Catalysis: How Structure Influences Catalytic Performance

“…There is much excitement at the prospect that SAC could bridge the gap between these fields [64], with isolated adatom active sites providing the extreme selectivity typical of homogeneous catalysts. The idea is then to target reactions typically performed by organometallic compounds in solution, and try to “heterogenize” the reaction using the same metal.…”

Single Metal Atom Photocatalysis

“…Therefore, downsizing metal nanoparticles to one single metal atom should be an effective approach to enhance the activity of a photocatalyst. Recently, single atom catalysts, which are defined as isolated metal atoms anchored on support, have drawn extensive research attention due to their unique catalytic properties . Different from traditional heterogeneous catalysts, single atom catalysts can achieve the maximum atom‐utilization efficiency, resulting in the reduced cost.…”
