Professor Saburo Hosokawa's research lab specializes in the development of advanced oxide materials with exceptional structural and redox stability for energy-related applications. The lab focuses on complex oxides such as Sr₃Fe₂O₇−δ, which exhibit unique topotactic oxygen insertion and extraction behavior, enabling high oxygen storage capacity and robust performance under extreme conditions. Key research directions include the design of functional oxides for solid oxide fuel cells, oxygen separation membranes, and sustainable energy conversion systems. The lab combines materials synthesis, structural characterization, and electrochemical analysis to explore fundamental mechanisms of oxygen ion transport and phase stability.
