Single‐Atom Catalysts for Hydrogen Activation

Small, 2023
AbstractSelective hydrogenation is one of the most important reactions in fine chemical industry, and the activation of H2 is the key step for hydrogenation. Catalysts play a critical role in selective hydrogenation, and some single‐atom catalysts (SACs) are highly capable of activating H2 in selective hydrogenation by virtue of the maximized atom ...

Single atom catalyst for electrocatalysis

Chinese Chemical Letters, 2021
Abstract Single atom catalyst (SAC) refers to a novel catalyst with the active metal atoms individually anchored on the support. Single atom catalysts present the unique appeal due to the high atomic availability and specific activity, as well as the high pathway selectivity.

Why do Single‐Atom Alloys Catalysts Outperform both Single‐Atom Catalysts and Nanocatalysts on MXene?

Angewandte Chemie International Edition, 2023
AbstractSingle‐atom alloys (SAAs), combining the advantages of single‐atom and nanoparticles (NPs), play an extremely significant role in the field of heterogeneous catalysis. Nevertheless, understanding the catalytic mechanism of SAAs in catalysis reactions remains a challenge compared with single atoms and NPs. Herein, ruthenium‐nickel SAAs (RuNiSAAs)

Toward Rational Design of Single-Atom Catalysts

The Journal of Physical Chemistry Letters, 2021
Downscaling catalyst size has long been used to promote the atomic utilization efficiency of catalysts. Single-atom catalysts (SACs) are the current end of this downscaling road, offering the potential of 100% metal atom utilization and excellent catalytic behavior compared with traditional nanoparticle catalysts.

Locally Ordered Single‐Atom Catalysts for Electrocatalysis

Angewandte Chemie International Edition, 2023
AbstractSingle‐atom catalysts manifest nearly 100 % atom utilization efficiency, well‐defined active sites, and high selectivity. However, their practical applications are hindered by a low atom loading density, uncontrollable location, and ambiguous interaction with the support, thereby posing challenges to maximizing their electrocatalytic ...
