Summary
Single-atom support catalysts embed metal atoms into supports, enhancing electrocatalysis. This review details atomic-level strategies for advanced catalysts in reactions like HER and OER.
Area of Science:
- Materials Science
- Electrochemistry
- Catalysis
Background:
- Single-atom catalysts offer high atom utilization but can lack cooperativity and stability.
- Metal-support interfaces are crucial for efficient electrocatalysis, demanding atomic-level control.
Purpose of the Study:
- To review atomic-level regulation strategies for single-atom support (SAS) catalysts.
- To extract structure-function principles for SAS-enabled composites in various electrocatalytic reactions.
- To outline future directions for SAS catalyst development.
Main Methods:
- Summarizing atomic-level regulation strategies for SAS catalysts.
- Analyzing structure-function relationships across multiple electrocatalytic reactions (HER, OER, ORR, CO2RR, NO3RR).
- Highlighting four key regulation modes: coordination, spin-state, defect, and geometric engineering.
Main Results:
- SAS catalysts enable strong metal-support interactions (SMSI), directional charge migration, and tunable coupling.
- Four regulation modes effectively tune electronic and geometric properties, impacting catalytic performance.
- Identified challenges include predictive design, operando characterization, unified descriptors, and scalable synthesis.
Conclusions:
- Atomic-level control via SAS strategies offers a powerful approach to designing high-performance electrocatalysts.
- A closed-loop roadmap integrating data-driven design and advanced characterization is proposed for future SAS catalyst development.
- Further research is needed to address challenges in predictive design, operando studies, and industrial scalability.

Heterogeneous 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...
Electrodes: Overview
Electrochemical measurements are conducted in an electrochemical cell composed of various components that control and measure the current and potential. One fundamental component is electrodes, conductive materials that enable electron transfer reactions at their surfaces.
There are two main types of electrodes in electrochemical cells. The first type, known as the working or indicator electrode, has a potential that is sensitive to the analyte's concentration and reacts to changes in the...

Processes at Electrodes
The electrode interacts with ions in the electrolyte solution at its interface. The rate of oxidation and reduction depends on the speed at which electrons can transfer through this interface. As ions attach to or leave the electrode surface, the electrode acquires a charge, and an electrical potential forms across the interface, making the process more difficult to reach equilibrium. The charge on the electrode affects the local ion concentrations in the solution, though thermal motion...
Introduction 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...
