Our research interests are focusing on the development of energy and environment related materials. In particular, we design and synthesize porous coordination networks (PCNs) and metal-organic frameworks (MOFs), which can be applied in hydrogen storage, carbon monoxide capture, and photo-catalyzed hydrogen generation. As the hydrogen storage materials, we are developing porous PCNs or MOFs that can store large amount of hydrogen at ambient temperature and pressure. The research involves fabrication of various metal nanoparticles in the frameworks. For carbon dioxide capture materials, we are synthesizing smart porous materials that can recognize and selectively adsorb carbon dioxide from the industry flue gas that contains not only CO₂ but also other gases. We are also investigating the molecular dynamics occurring in the crystals of porous frameworks in response to external stimuli, which can be applied in the development of new type of sensors and devices. The research uses techniques and instruments such as FTIR, UV-NIR, NMR, EPR, GC, powder and single crystal X-ray diffraction analysis, TG/DSC analysis, HRTEM, SEM, XPS, EDS, SQID, low pressure and high pressure gas sorption measurements, etc.
