Summary
A new low-hydroxyl-coverage surface collision (LSC) strategy enables scalable synthesis of single-atom materials (SAMs) for diverse applications. This method offers a sustainable, industrial platform for producing high-performance SAMs, overcoming previous manufacturing limitations.
Area of Science:
- Materials Science
- Chemical Engineering
- Environmental Science
Background:
- Single-atom materials (SAMs) show great potential in chemical engineering, energy, and environmental remediation.
- Current synthesis methods for SAMs lack scalability and sustainability, hindering practical applications.
Purpose of the Study:
- To develop a scalable and sustainable synthesis strategy for universal single-atom materials.
- To establish an industrial platform for manufacturing high-performance SAMs.
Main Methods:
- A low-hydroxyl-coverage surface collision (LSC) strategy using amino acids to control surface hydroxyl coverage.
- Preparation of various single-atom materials (Fe, Co, Ni, Mn, Mg, Al) on (hydr)oxide supports.
- Design of a production facility with a 1-ton daily capacity, reducing carbon emissions by 67.8-72.0%.
Main Results:
- Gram to ton scale production of universal single-atom materials achieved.
- A representative Fe1-OLa single-atom material demonstrated effective phosphorus removal (98.7%) from eutrophic lake water.
- The LSC strategy overcomes traditional mass/heat transfer and solvent use limitations.
Conclusions:
- The LSC strategy provides a general and industrial platform for manufacturing high-performance single-atom materials.
- This work bridges the gap between laboratory research and large-scale engineering applications for SAMs.
- The developed method offers a sustainable approach to SAM production with significant environmental benefits.
