Nanoscale chemical imaging of the reduction behavior of a single catalyst particle.
A closer look: Investigation of the reduction properties of a single Fischer-Tropsch catalyst particle, using in situ scanning transmission X-ray microscopy with spatial resolution of 35 nm, reveals a heterogeneous distribution of Fe(0), Fe(2+), and Fe(3+) species. Regions of different reduction properties are defined and explained on the basis of local chemical interactions and catalyst morphology.
