In Situ XRD Cell
An in situ reaction cell has been developed for a commercial X-ray diffractometer (XRD) in order to characterise materials including catalysts under reaction conditions. Such a cell facilitates real-time characterisation of materials and permits the rapid structural changes to be observed as they happen, increasing understanding of the changes which they undergo during exposure to different environments.
Advantages over commercially available in situ cells include minimised dead volume and the possibility of co-feeding gases such as water vapour.
The newly designed in situ cell uses a capillary tube (75 mm long and outer diameter of 1 to 2 mm) as the reaction vessel that can withstand pressures more than 20 bar and temperatures up to 500°C. This first-of-its-kind design can be mounted on any commercial XRD and it can be used both with conventional diffractometers and in conjunction with synchrotron facilities.
