Researchers from the Korea Institute of Materials Science (KIMS) and KAIST have developed a cutting-edge catalyst that significantly enhances carbon dioxide (CO₂) conversion. This innovation transforms CO₂ into valuable chemical fuels with twice the efficiency of conventional methods. Opening the doors for further CO₂ conversion technology.

Overcoming Efficiency Barriers

Traditional CO₂ conversion methods are energy-intensive and inefficient. Single-atom catalysts (SACs) show promise but struggle with stability. To solve this, the research team introduced dual-single-atom catalysts (DSACs), which leverage interactions between two metal atoms for greater efficiency and selectivity in CO₂ hydrogenation.

Optimized Catalyst Design

By carefully controlling oxygen vacancies and defect structures in metal oxides, the new DSAC technology significantly improves CO₂ and hydrogen (H₂) adsorption. As a result, it leads to a far more effective reaction. Consequently, this results in a highly efficient conversion process that achieves over 99% selectivity and effectively doubles efficiency.

Simplified Production for Commercialization

Using aerosol-assisted spray pyrolysis, the team developed a streamlined synthesis process that eliminates complex steps. This scalable method cuts single-atom catalyst usage by 50% while ensuring high efficiency.

This breakthrough paves the way for applications in chemical fuel synthesis, hydrogen production, and clean energy, making CO₂ conversion technology more viable for a sustainable future.
