Research Overview

Tailoring functional ceramics for environmental and energy-related applications.

Research Subjects

  • 1.Tailoring of functional ceramics based on the crystal chemistry approach.
  • 2.Development of oxygen storage materials and their applications in environmental and energy-related fields.
  • 3. Electronic property control of transition metal oxides.
  • 4.Development of proton conductors for solid oxide fuel cells.

Introduction:

We are working on functional ceramics for environmental and energy-related applications. Driven by critical global issues, such as environmental destruction and energy depletion, developing innovative functional materials is a major scientific challenge. Our laboratory investigates inorganic materials, especially oxides with significant activity for oxygen-related reactions, because oxygen is a key element in fields of energy and industry. Our goal is to develop oxygen storage materials that exhibit excellent oxygen intake/release for future applications such as oxygen gas generation, chemical fuel production, and next-generation batteries.
