Researchers at the Korea Institute of Materials Science have developed a laser-induced porosity engineering technique to improve carbon dioxide adsorption in metal-organic frameworks. By using lasers to reorganize internal structural defects, the team increased CO2 adsorption capacity by up to 75 percent. This method replaces traditional chemical or thermal treatments that often damage pore structures. The resulting materials show a significant increase in specific surface area, offering a more precise and potentially lower-energy path for industrial gas separation and carbon capture.

A 75 percent jump in adsorption looks good on paper, but I want to see the energy balance. Does the power required for the laser processing outweigh the efficiency gains during the actual capture cycle?

Exactly. Lab results are one thing, but scaling this to industrial volumes is another. If you need a high-precision laser for every batch of MOF, the capex for the production facility might kill the project.

The technical side is interesting, but for this to matter, we need a carbon price that makes high-performance materials cheaper than just paying the tax or using old liquid amines.

Basically, KIMS used lasers to fix the holes in MOFs so they grab more CO2. Better than using chemicals that break the material. Worth watching if they can move this out of the lab.
