Professor Kengo Shimanoe's research lab specializes in the development of advanced functional materials for energy and environmental applications. The lab focuses on designing and synthesizing novel oxide-based materials, particularly perovskite-type oxides and composite nanomaterials, for applications in oxygen separation, gas sensing, and clean energy conversion. Key research directions include the fabrication of asymmetric membranes for high-efficiency oxygen permeation and the engineering of nanostructured metal oxides for highly sensitive and selective detection of toxic gases such as carbon monoxide. The lab combines materials synthesis, structural characterization, and performance evaluation to address challenges in sustainable energy and environmental monitoring.

High oxygen permeability was achieved using an asymmetric Ba0.95La0.05FeO3−δ membrane. In this membrane, oxygen diffuses physically through pores of a porous support and oxygen permeates electrochemically through a dense layer. The oxygen permeation flux of the asymmetric Ba0.95La0.05FeO3−δ membrane reached more than 10 cm3 (STP) min−1 cm−2 from a test gas containing 50% oxygen at 930 °C.

Clustered indium oxide/copper oxide (In<sub>2</sub>O<sub>3</sub>/CuO) nanospheres with different CuO amounts were successfully synthesized as sensing materials for the carbon monoxide (CO) detection. Component and morphological characterizations were performed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Sensing performance for CO of the clustered In<sub>2</sub>O<sub>3</sub> and In<sub>2</sub>O
