Professor Junichiro Otomo's research lab specializes in advanced materials and electrochemical processes for sustainable energy conversion and carbon management. The lab focuses on developing efficient oxygen carriers and catalysts for chemical looping systems, particularly for biomass combustion and ammonia synthesis, with an emphasis on enhancing reaction kinetics and structural stability. Key research directions include proton-conducting electrolytes for intermediate-temperature ammonia production, electrode design for electrochemical processes, and the modification of iron-titanium oxides to improve reactivity and durability in redox cycles. The lab integrates materials characterization, microstructural analysis, and electrochemical testing to advance clean energy technologies.

A coupled analysis of the reaction kinetics and microstructural changes of Fe2O3/Al2O3 oxygen carriers during redox reaction cycles for chemical looping systems was conducted. The microstructural changes in the oxygen carrier particles were investigated using an image analysis method with cross-sectional backscattered electron images, and microstructural information such as the particle size, porosity, and two-phase boundary between the iron oxide and pores was obtained. The microstructural chan
