AB Catalytic bodies of millimetric dimensions are frequently usedin industrial catalysis. The engineering process applied on theraw nanocatalyst during the fabrication and the workingconditions affect the spatial and chemical relations of theexposed surface of the catalytic device. Hence, for improvingtheir synthesis and for monitoring the evolution during its lifecycle it is important understanding the actual heterogeneitiesof their surfaces. In this work scanning electron microscopy,photogrammetry and X-Ray spectroscopy are combined toperform physico-chemical characterization in three-dimensionsand with high resolution of the surface of commercial water gasshift catalyst bodies. By analyzing a phase of carbon present ontheir surface we show that the method provides measurementsthat are at the same time reliable, accurate and precise.
