관심분야 Research Interest
My research interests on materials issues related with environment and energy. Currently, my group is focusing on two separate projects. In one of them, we are trying to develop CO2absorbentsthatcanbeusedrepetitivelyinthetemperaturerangeof300-500°C. Such a material is considered to be an integral part for the development of a carbon capture process which may become a major workhorse in reducing the emission of CO2and,hence,inaddressingtheissueofglobalwarming.Intheotherproject,wearetryingtounderstandandutilizesonochemistryinobtainingnovelnanomaterials.Especially,wehavedevelopedanewreactionschemetosynthesizecore-shellnanoparticleswithPtintheshellandvariousmetalsinthecore,whichfeaturesarehighlysoughtforinmanyapplicationfieldsincludingcatalysisforfuelcells.
