Kameoka Lab
Machine-translated · View original
A lab that takes a metallurgical approach to developing new metal catalysts and quasicrystals.
AboutAbout the lab
New catalysts from a metallurgical perspective
The Kameoka Lab conducts fundamental research and materials development on metals and alloys with new structures and functions, based on a metallurgical perspective.
The core of its research is the design and preparation of metal and alloy catalysts with excellent catalytic performance, using bulk metals as the starting material.
The lab develops processes for creating new catalytic materials by applying activation treatments such as leaching, hydrogen absorption, and oxidation to metals and alloys.
It also works on the synthesis and structural analysis of quasicrystal-related materials (hypermaterials), exploring their potential as catalytic materials.
Key terms
- Catalyst
- A substance that makes a chemical reaction proceed more easily without itself being changed
- Intermetallic compound
- An alloy in which atoms of multiple metals are arranged in fixed proportions and in an orderly way at fixed positions in the crystal lattice
- Quasicrystal
- A solid in which atoms are arranged according to a non-repeating rule. Its symmetry differs from that of ordinary crystals

ResearchResearch themes
The core of the lab's research is the design and preparation of metal and alloy catalysts with excellent catalytic performance, using bulk metals as the starting material. It aims to create materials that combine a unique metal microstructure with catalytic functions, which cannot be obtained with the perspectives and methods of conventional catalytic chemistry.
*Illustrative imageUsing bulk alloys as catalysts
Rather than the well-reported nanoparticle or supported catalysts of metals and alloys, the lab uses the bulk alloy itself as the catalytic material. This is still an unexplored area of research.
*Illustrative imageAlloy catalysts to replace precious metals
Precious metals such as rhodium are rare and expensive. From two perspectives, controlling the electronic structure and controlling the metal microstructure, the lab develops catalytic materials that can replace precious metals.
*Illustrative imageCatalysts made from intermetallic compounds
Intermetallic compounds are alloys in which the constituent atoms are arranged in an orderly way at fixed positions in the crystal lattice. By controlling their microstructure, the lab designs and prepares new catalytic materials.
*Illustrative imageUsing metal foils as catalysts
Metal foils offer excellent workability, heat conduction, and permeability to substances, giving them features that differ from nanoparticle catalysts. The lab makes foil-type catalysts through microstructure control and processing.
