[Asia Economy Reporter Junho Hwang] Domestic researchers have developed a new material that generates heat upon contact with water. This material releases heat three times more than magnesium oxide with similar properties, making it a promising material for storing industrial waste heat generated during the production processes of metals, glass, and pulp as chemical energy.
The research team led by Dr. Hyunwook Kim from the Energy Materials Research Laboratory at the Korea Institute of Energy Research announced on the 15th that they developed a new metal-organic framework called SKIER-2 (MgO@NC), which was featured as a cover paper in the journal ACS Applied Nano Materials.
This material addresses the weakness of magnesium oxide-based materials, which have been noted for waste heat storage but suffer from low thermal conductivity. It is a new material synthesized by using magnesium oxide-based substances as structural units, heat-treated at 700℃, and dispersed between porous carbon nano layers.
This material exhibited heat release three times higher than existing materials and showed thermal conductivity more than 4.5 times higher than typical magnesium oxide-based waste heat storage materials.
The research team explained, "This high heat release and thermal conductivity are attributed to a surface area approximately 76 times larger than conventional materials and uniformly dispersed nanosized magnesium oxide particles, as revealed by surface area measurements and high-resolution electron microscopy analysis."
