Speaker: Dr. Jonas Jacobs, Martin-Luther-Universität Halle-Wittenberg.

Topic:
Solid-state reactions often resemble “black boxes” due to their complex parameter spaces, typically requiring extensive and time-consuming trial-and-error experimentation. Even when a pure product is obtained, information about the reaction pathway is frequently lacking, hindering the discovery of intermediate phases or alternative compositions and morphologies. Time- and temperature-resolved in situ X-ray diffraction (XRD) has proven to be a powerful tool for elucidating reaction mechanisms by enabling the direct observation of intermediates and allowing for improved control over solid-state syntheses.
In this contribution, we introduce a low-cost capillary reactor designed for in situ XRD experiments, coupled with mass spectrometry (MS). This setup enables simultaneous monitoring of both structural and gas-phase evolution, providing enhanced insight into reaction atmospheres and parameter spaces. This approach allows for more systematic optimization and deeper understanding of complex solid-state transformations.
