A research team led by Hee-jung Lee, senior researcher at Korea Institute of Materials Science (KIMS), in collaboration with Professor Sunghwan Park of Kyungpook National University and Professor Mingyu Kim of Yeungnam University, has developed a technology that enhances CO₂ adsorption performance in metal–organic frameworks (MOFs) by up to 75% through precise laser-based control of their internal structure.
The study, published in the journal Small, demonstrates a new approach to improving material performance through laser post-treatment, offering an efficient alternative to conventional complex chemical processing methods.
Why better gas separation is crucial
The separation of mixed gases such as carbon dioxide (CO₂) and methane (CH₄) is essential for applications such as natural gas purification and improving energy efficiency, and is considered a key technology for achieving carbon neutrality.
