Hard X‐ray Nanotomography of Catalytic Solids at Work

A closer look at catalysis: In situ hard X-ray nanotomography has been developed (see picture) as a method to investigate an individual iron-based Fischer–Tropsch-to-Olefins (FTO) catalyst particle at elevated temperatures and pressures. 3D and 2D maps of 30 nm resolution could be obtained and show heterogeneities in the pore structure and chemical composition of the catalyst particle of about 20 μm.
