Nanochemistry laboratory has been fabricating new functional inorganic nanomaterials such as noble metal-based nanocrystals, and magnetic nanoparticles which are applicable in various electrocatalysis, organic reactions, biomedical and environmental applications.

Noble Metal-based Catalysts

Our group focuses on designing new cost-effective alternative nanomaterials for various electrocatalysis and organic compound conversion. Research areas include the utilization of inexpensive transition metals to minimize the use of scarce precious metals yet maximize both activity and stability of the alloy composites. Chemical Vapor Deposition (CVD) is the main fabrication process for the formation of size, shape, and phase control of pure nanocrystals with different structures involving core-shell, high defect, or lattice distortion.

Magnetic Nanoparticles

The highest magnetization and ultra-stable FeCo nanoparticles encapsulated in graphitic carbon shell (FeCo/GC) system, which is a new multi-functional inorganic nanomaterials, has been successfully adopted. We have been carrying out surface functionalization of the nanoparticles with biocompatible materials for biomedical applications such as MRI contrast agents, biomaterial separation, and photo-heat conversion treatment. Also, variety of functional groups have been aiming to graft on the carbon shell for efficiently implement the material in environmental remediation including heavy metals capturing and degrading of both organic and inorganic pollutants.
