Research target
My research target is graphitic carbon nitrides, called as g-CNs.
The g-CNs are shown in left.
They have a variety of structures, but all of them have a two-dimensional covalent structure between carbon and nitrogen, and are literally "graphitic" materials.
Also, they exhibit unique properties.
- H2 generation
- CO2 reduction
- Dark photocatalysis
- Photochromism
Based on these details, g-CNs have potential to be applied as a material for solar energy conversion.
techniques
My mainly techniques to analyze materials.
PES and IPES
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.
