Yokoi Lab
Machine-translated · View original
A lab that uses zeolites with nanoscale pores to turn carbon resources into useful chemicals.
AboutAbout the lab
Nanoscale space changes how chemicals are made.
The Yokoi Lab studies materials with nanoscale spaces, such as zeolites and mesoporous materials.
Its goal is to freely control the structure of these spaces and give them function, creating "nanospace catalysts."
The lab develops catalysts, and the processes that use them, that can convert the diverse carbon resources on Earth into useful chemicals.
This contributes to using resources without waste and making chemical production processes greener.
Key terms
- Zeolite
- An oxide of silicon and aluminum with regularly arranged nanosized pores
- Catalyst
- A substance that makes a chemical reaction proceed more easily without being changed itself
- Mesoporous material
- A porous material with regularly arranged pores a few to several tens of nanometers wide

ResearchResearch themes
The lab aims to freely control the structure and function of the spaces in zeolites and mesoporous materials, which have nanoscale spaces. It works on developing "nanospace catalysts" that convert the diverse carbon resources on Earth into useful chemicals, along with the catalytic processes that use them.
*Illustrative imageDevelopment of Nanospace Catalysts
The lab controls the positions and distribution of aluminum, titanium, gallium, and other elements incorporated into zeolite frameworks, and also develops methods to evaluate them. It also works with spherical mesoporous silica of uniform size and silica nanoparticles with precisely controlled particle diameter.
*Illustrative imageDevelopment of Catalytic Reaction Processes
The lab develops zeolite catalysts that produce light olefins from carbon dioxide and non-fossil resources. It also covers difficult selective oxidations, such as methane to methanol and benzene to phenol, and the synthesis of chemicals from biomass.
*Illustrative imageDevelopment of Advanced Structural Analysis and Characterization Methods
To design materials and elucidate reaction mechanisms, the lab examines zeolite structures and the distribution of acid sites using solid-state NMR and in situ FT-IR. It also observes the surfaces and interiors of porous material particles with low-voltage scanning electron microscopy.
