Appl. Crystallogr. 46 262–266 (2013) doi:10.1107/s0021889812042781
Improving industrial processes has become one of the major worldwide challenges. In heterogeneous catalysis, chemical reactions take place at the surface of the material and can be influenced by its structure. To better understand the impact of the material surface and structures on catalytic properties, it is important to characterise them simultaneously. The association of X-Ray Diffraction (XRD) and Diffuse Reflectance Infrared Fourier Transform (DRIFT) spectroscopy, combined in a single dedicated high temperature and high pressure reaction cell with online Gaseous Chromatograph (GC) can be the answer to this challenge. For the first time, such an analytical tool is developed for laboratory applications. The use of this device is illustrated and validated through the in situ study of calcium oxalate thermal decomposition
