%X Catalytic bodies of millimetric dimensions are frequently used
in industrial catalysis. The engineering process applied on the
raw nanocatalyst during the fabrication and the working
conditions affect the spatial and chemical relations of the
exposed surface of the catalytic device. Hence, for improving
their synthesis and for monitoring the evolution during its life
cycle it is important understanding the actual heterogeneities
of their surfaces. In this work scanning electron microscopy,
photogrammetry and X-Ray spectroscopy are combined to
perform physico-chemical characterization in three-dimensions
and with high resolution of the surface of commercial water gas
shift catalyst bodies. By analyzing a phase of carbon present on
their surface we show that the method provides measurements
that are at the same time reliable, accurate and precise.
