Catalysts produced by in situ exsolution have recently been introduced to overcome the practical drawbacks of traditional nanometal catalysts. The exsolution material is a kind of supported nanocatalyst prepared by designing a perovskite oxide support that could exsolve a catalytically active nanometal catalyst on its surface. Our group is dedicated to investigate the growth mechanism of nanoparticle and application such as electrochemical devices, reforming catalyst and gas sensors.


Nanocomposite electrodes have attracted considerable attention as innovative solutions for maximizing the density of triple-phase boundaries (TPBs) and facilitating efficient ionic conduction pathways, thereby exhibiting high performance at intermediate temperatures (500–700 °C). Most nanocomposites have been used as air electrodes in fuel electrode- and electrolyte-supported cells because of their relatively low sintering temperatures (700–900 °C). Our group is engaged in developing new nanocomposite electrode configurations that extend their application beyond air electrodes and fuel cells.
