What is catalyst technology?

"We have worked in collaboration with various research institutions, starting with joint research with the late Masatake Haruta (*), who was the first researcher to clarify the catalytic activity of gold, to develop catalysts that decompose offensive odors and harmful gases.
Furthermore, we develop catalyst bodies for various applications by immobilizing nanoparticle catalysts onto various filter substrates through the application of our proprietary nanoparticle immobilization technology (Nafitec™). We provide catalytic filters and removal systems that remove harmful gases by selecting nanoparticle catalysts in accordance with the customer’s applications and target gases.

Features

[1] Activation by increasing the surface area of the catalyst

The larger the surface area of catalyst particles, the greater the area that is in contact with the target gas, and consequently, the more likely they are to cause a catalytic reaction or chemical reaction. By transforming catalyst particles into nanoparticles, it is possible to obtain sufficient catalytic reactions, powerful catalytic reactions, and chemical reactions with a smaller amount of particles than conventional particles that are submicron (several hundred nm) or larger in size.

[2] Transformation of nanoparticle catalysts into filters

When using a nanoparticle catalyst for a filter or other application, the nanoparticle catalyst needs to be immobilized onto a base material (honeycomb, non woven fabric, porous metallic material, bead, etc.). With Nafitec™, which is NBC Meshtec’s proprietary technology that can immobilize nanoparticles even onto base materials with complicated shapes, it is possible to develop highly versatile catalytic filters.
