Analyses of Catalysts, Ultrafine Particles, and Nano Materials

Ultrafine particles of 100 nm or less in diameter are strongly affected by surface effects compared to bulk. In analysis of nano particles and ultrafine particle, this property is utilized.

In order that the capability of ultrafine particles by means of surface effect is fully exerted, JFE-TEC analyzes morphology, composition, diffusion state and surface chemical state of particles and undertakes structure analysis necessary for design of fine particle material or failure analysis.

Analysis of Catalyst

JFE-TEC conducts atomic- to macro-scale analysis of composition, morphology (particle diameter/shape, dispersion state, and particle size distribution), surface chemical state (oxidation, reduction, etc.), absorption, and state of dispersed particles/carrier and parent phase interface of catalyst.
