Functional Nanomembranes and CO2 Separation Lab
Machine-translated · View original
The lab develops nanomaterials aimed at capturing CO₂ and harnessing light.
AboutAbout the lab
Tomorrow's nanoengineering, taking the world one step ahead
The Fujikawa Lab develops materials whose structures are designed from the molecular level up to the nanoscale, based on materials chemistry.
The lab regards atmospheric carbon dioxide and the sunlight falling from the sky as "ubiquitous" sources of carbon and energy that are available anywhere.
It aims to open up a new field called carbon-neutral chemistry, in which these substances and this energy are used effectively.
Key terms
- Ubiquitous
- A word describing something that exists anytime and anywhere. Atmospheric CO₂ and the sunlight falling from the sky are examples.
- Direct Air Capture
- A technology that captures CO₂ directly from the atmosphere, taking carbon back out of the air.
- Nano-kenzan
- A structure in which silicon nanowires stand densely and vertically, spaced tens of nanometers apart.

ResearchResearch themes
To make effective use of materials and energy available anywhere, such as atmospheric carbon dioxide and sunlight, the lab develops materials with structures designed at the nanoscale. Working on separation nanomembranes, light-harvesting surfaces, and interfaces with nanospaces, it aims to pioneer carbon-neutral chemistry.
*Illustrative imageSeparation Nanomembranes for Capturing CO₂ from the Air
The lab develops separation membranes for Direct Air Capture, a technology that captures carbon dioxide directly from the atmosphere. It focuses on "giant nanomembranes": membranes that are free-standing even though they are only nanometers thick, and whose flat area is large enough to hold in the hand.
*Illustrative imageLarge-Area Surfaces That Harvest Light
To harvest sunlight efficiently, the lab precisely controls the surface structure of materials at the nanometer level and creates large-area surfaces that respond to light in distinctive ways. It is also advancing the fabrication and application of large-area arrays of noble metal nanoparticles.
*Illustrative imageFunctional Interfaces Using the "Nano-Kenzan" Structure
The lab focuses on the "nano-kenzan" structure, in which silicon nanowires stand densely and vertically like a forest. Using the gaps between the wires as reaction spaces and immobilizing catalyst nanoparticles there, it has realized conversion systems that carry out a variety of organic reactions with high efficiency.
*Illustrative imageGas Separation with Composite Nanomembranes
Membrane separation is considered a promising technology for separating CO₂ from exhaust gas. By thinning selective membranes and modifying membrane surfaces, the lab develops new membranes with excellent separation performance.
