Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…
