Heterogeneous metal catalysts are amongst the most important industrial catalysts. During catalyst preparation it is of high interest to yield a stable and highly dispersed active metal phase. The reduction of these catalysts is a vital step in the catalyst preparation as it determines the dispersion and thereby activity. There has been a wealth of investigations on the mechanism of reduction, however, most studies were performed either ex-situ or with model systems.
This project focuses on gaining insights into the reduction mechanisms of nickel catalysts. In that respect, it is vital to study the evolution of the active phases of typical catalysts with a combination of complementary techniques. Along with the understanding thus generated, the project aims at improving the synthesis of current catalysts by influencing the reduction processes and beyond that leading to new and improved catalyst properties.
