Figure 16
Speciation maps at the Fe K-edge and Cu K-edge derived from MCR-ALS minimization of the hyperspectral imaging dataset (180 cubes) measured during the monitoring of the activation of the FeCu/SiO2 catalyst under H2 for selected temperatures. The pixel size is 32.5 µm × 32.5 µm. The color bar is related to the fraction of species. The heater is located at the bottom of the image. The flow of hydrogen is from the right to the left of the capillary.
