Inorganic Chemistry
Single Crystal X-ray Analysis
SKKU organometallic chemists are designing and synthesizing new organometallic compounds. The structure of organometallic compounds can be precisely characterized by single crystal X-ray analysis. Single crystals of new organometallic compounds are grown by the specific methods including the slow diffusion of poor solvent to the solutions of new organometallic compounds. With a help of computational programs, the structure of new organometallic compounds can be visualized.
Inorganic Chemistry
Electrocatalysts
SKKU materials chemists are designing and synthesizing new electrocatalysts to be used in fuel cells. Electrocatalysts based on nanoparticles with low Pt-contents are the key step for the commercialization of fuel cells and for the introduction of the ‘Hydrogen Economy’. Novel methods to synthesize such electrocatalysts are being pursued. Various sophisticated analysis methods are also used to probe the fine structures of the nanoparticles and to assess their electrochemical properties, many of which are through domestic and international collaborations.
Inorganic Chemistry
Solar Cells
SKKU materials chemists focus on the study of photovoltaic cells prepared by compound semiconductors such as copper-indium-gallium-selenium. The new precursor compounds for the absorber layers are synthesized in the form of single crystals, polycrystalline, which are analyzed to develop the novel thin film technology. The precursor solution coating and nano-ink type deposition are applied to low-cost fabrication methods of the solar cells.
Inorganic Chemistry
Batteries
SKKU materials chemists are engineering mesoporous and nano-structured electrode materials to enhance the present performance of secondary batteries. Energy storage devices such as supercapacitors and batteries consist of various chemical components which require continuing studies. Especially, the chemists are developing high performance cathode and anode materials, flexible current collectors, separator membranes, new electrolytes, and unprecedented batteries.
Inorganic Chemistry
Green Catalysis
SKKU organometallic chemists are designing and synthesizing new catalytic systems for biomass conversions and carbon dioxide utilization. The plants are important sustainable chemical resources (biomass) to replace the depletable petroleum chemistry. The conversions of biomass to furan derivatives are important and can be promoted by catalysis. In addition, very efficient catalysts are required to fix and convert the carbon dioxide to useful chemicals. SKKU applied organometallic chemists are developing new catalytic systems based on microporous organic network chemistry.
