I'm reserching about


I'm a master student in functional materials science especially researching energy-conversion photocatalytic materials. In order to improve the performance of materials, we are working on materials synthesis and analysis, mainly evaluating from fundamental viewpoints such as electronic and crystal structures.

Currently, I'm working on carbon nitride polymers that exhibit photocatalytic activity in response to visible light.

My mainly techniques to analyze materials.


photoelectron spectroscopy(PES) and inversed photoelectron spectroscopy(IPES) are techniques to analyze the electronic structure of materials by observing the relative energies of electrons in atoms and molecules.

X-ray diffraction

X-ray diffraction(XRD) is a technique to determining the atomic and molecular structure of a material by measuring the angles and intensities of these diffracted beams.

DFT calculation

It is a method for calculating the electronic structure and optimized structure of materials based on the density functional theory. When combined with XRD and PES/IPES, it is a powerful method of material analysis.

Exploring new applications of poly(heptazine imide), which have never been explored before.
Poly(heptazine imide) called as PHI, one of the graphitic carbon nitrides, has been mainly studied for photocatalytic applications. On the other hand, PHI has characteristic properties such as encapsulation Alkali ions in the structure, a strong three-fold symmetry framework, and long lived excited states. I am convinced that these unique properties of PHI will lead to new applications not found in conventional graphitic carbon nitirides.
