Identifying and Mitigating Adverse X‑ray Induced Effects in Operando Spectroscopic Studies of Copper Exchanged Zeolites.

ABSTRACT: The increase in brilliance and global proliferation of synchrotron facilities has established synchrotron radiation as an indispensable tool in modern science. However, as synchrotron sources become more powerful, the risk of X-ray induced alterations becomes increasingly pronounced. These beam-induced effects will compromise results, leading to unusable data at best and incorrect conclusions at worst. Techniques that guarantee that the means of observation do not cause the observed phenomena are therefore an absolute necessity. This work presents a methodology to mitigate beam-induced effects, consisting of performing a mesh scan  in which the beam is rastered across the sample bed  to avoid local overexposure. The validity of this approach is demonstrated using copper-exchanged zeolite
