Schematic view of the experimental setup. The diffraction pattern from the (100) surface was detected in the forward direction with respect to the incoming X-rays. The laser sheet, with a wavelength of 2.7 µm, used to probe the CO2 gas phase, was sent through the reactor at an angle of approximately 45° relative to the X-rays. The camera for CO2 detection was positioned perpendicular to the laser sheet. In addition, an MS was connected to the outlet of the reactor to measure the global gas concentration. |
