Catalyst architecture research, testing and analysis
Intertek investigates and analyzes catalyst architecture and structure for clients.
Manufacturing methods can lead to different catalyst architectures. For example, impregnation may result in a uniform distribution of active species or an "egg-shell" structure. Cross-sections made for SEM by embedding cutting and polishing or by FIB (Focused Ion Beam) can enable the measurement of depth profiles on mm sized supports. On a finer scale, TEM/STEM analysis on samples prepared by microtomy and/or FIB thin sectioning can provide even greater detail.
EDX analysis of clusters of particles at the 1 micron, 100n and 10nm scales can provide data on mixing or segregation in co-precipitated systems. In some cases EDX mapping reveals the architecture at the primary particle level.
The Intertek MSG laboratory is staffed with scientists who are experts in analyzing catalyst architecture.
