Summary
Single-atom catalysts (SACs) performance hinges on their coordination environment. This review details how engineering the local structure and metal-support interactions optimizes SACs for electrocatalysis.
Area of Science:
- Materials Science
- Catalysis
- Electrochemistry
Background:
- Single-atom catalysts (SACs) offer high atom efficiency and unique properties.
- The central metal atom's activity in SACs is modulated by its coordination environment.
- Understanding metal-support interactions and coordination spheres is key to SAC optimization.
Purpose of the Study:
- To provide an atomic-level, descriptor-driven analysis of coordination effects on SAC electrocatalytic performance.
- To emphasize the synergistic interplay between metal atoms and their coordination spheres.
- To review advanced synthesis strategies and characterization techniques for SACs.
Main Methods:
- Literature review focusing on coordination effects and electronic descriptors.
- Analysis of structure-activity relationships in SACs for key reactions.
- Integration of operando spectroscopy, microscopy, and theoretical calculations.
Main Results:
- Coordination environment critically influences SAC activity, selectivity, and stability.
- Synergistic effects between metal atoms and ligands activate reaction intermediates.
- Advanced synthesis and characterization methods reveal structure-performance correlations.
Conclusions:
- Precise regulation of the coordination sphere is essential for high-performance SACs.
- Future research should focus on advanced synthesis, operando studies, and theoretical modeling.
- Coordination-regulated SACs hold significant promise for electrocatalysis, including water splitting and CO2 reduction.

01:22Heterogeneous Catalysis
Heterogeneous catalysis involves a catalyst in a different phase from the reactants. It is a process where the catalyst and the reactants are in distinct phases, typically solid and gas or liquid.Most heterogeneous catalysts are metals, metal oxides, or acids. The list includes transition metals like iron (Fe), cobalt (Co), nickel (Ni), palladium (Pd), platinum (Pt), chromium (Cr), manganese (Mn), tungsten (W), silver (Ag), and copper (Cu). These metals possess partially vacant d orbitals that...
01:13Introduction to Mechanisms of Enzyme Catalysis
For many years, scientists thought that enzyme-substrate binding took place in a simple "lock-and-key" fashion. This model stated that the enzyme and substrate fit together perfectly in one instantaneous step. However, current research supports a more refined view scientists call induced fit. The induced-fit model expands upon the lock-and-key model by describing a more dynamic interaction between enzyme and substrate. As the enzyme and substrate come together, their interaction causes a mild...

01:27Catalysis
Catalysis influences the rate of chemical reactions by providing an alternative reaction pathway with lower activation energy. A catalyst speeds up a reaction, but it is not consumed during the process. The fundamental principle of catalysis is the ability of a catalyst to alter the reaction mechanism, often introducing a more efficient pathway than the uncatalyzed process.In a catalyzed reaction, the catalyst participates directly in the reaction mechanism. It interacts with reactants to form...
02:50Catalysis
The presence of a catalyst affects the rate of a chemical reaction. A catalyst is a substance that can increase the reaction rate without being consumed during the process. A basic comprehension of a catalysts’ role during chemical reactions can be understood from the concept of reaction mechanisms and energy diagrams.
01:26Thermal and Photochemical Electrocyclic Reactions: Overview
Electrocyclic reactions are reversible reactions. They involve an intramolecular cyclization or ring-opening of a conjugated polyene. Shown below are two examples of electrocyclic reactions. In the first reaction, the formation of the cyclic product is favored. In contrast, in the second reaction, ring-opening is favored due to the high ring strain associated with cyclobutene formation.
