Project duration : 36 months

T he presented project meets the most expected needs for the development of a new methodology that will allow observation of the richness and nature of the surface structure, using for this purpose modern in situ and operando spectroscopy methods (Raman, IR, UV-Vis) and their combinations with microscopic techniques. Surface spectroscopic measurements should ideally be carried out under real catalytic conditions. In situ measurement refers to any spectroscopic measurement that is carried out under given reaction conditions, which gives a better insight into the catalytic process. A new term for operand spectroscopy was introduced to literature in the field of catalysis at the beginning of the 21st century. Its significance determines the special importance of combining the basic method of surface spectroscopy with the catalytic process occurring at the same time and in the same sample, under real reaction conditions. Understanding the path of transformation that a substrate molecule performs in the process of transformation into a product, its way of interacting with the surface of the catalytic material is a challenge that drives curiosity. Although many chemists have put a lot of effort into explaining catalytic processes, the number of cases requiring deeper understanding is still increasing.
