Book Description
Unlike homogeneous catalysts, heterogeneous catalysts that have been optimized through decades are typically so complex and hard to characterize that the nature of the catalytically active site is not known. This is one of the main stumbling blocks in developing rational catalyst design strategies in heterogeneous catalysis. We show here how to identify the crucial atomic structure motif for the industrial Cu/ZnO/Al2O3 methanol synthesis catalyst. Using a combination of experimental evidence from bulk-, surface-sensitive and imaging methods collected on real high-performance catalytic systems in combination with DFT calculations. We show that the active site consists of Cu steps peppered with Zn atoms, all stabilized by a series of well defined bulk defects and surface species that need jointly to be present for the system to work.

Book Description
The goal of this research is to develop a better understanding of the mechanism of alcohol synthesis from CO/H2 by adding probe molecules (principlely, CH3NO2) to the dynamic reaction mixture and following how the added probe molecule is incorporated into the products to distinguish the dominant pathways from the possibilities proposed in the literature. Cu/ZnO/Al2O3 and Co/Cu/ZnO/Al2O3 catalyst systems have been chosen for this study. It is well known that Cu/ZnO methanol synthesis catalysts can be made into higher alcohol synthesis catalysts by adding alkali metal (Cs, K, Na). The inclusion off Group VIII metals (Co, Fe) for the same purpose has been studied to a much lesser extent. Few mechanistic studies of the Co/Cu/ZnO/Al2O3 have been reported in the literature. Study of a catalyst system consisting of both Group VIII metal and well-known methanol synthesis catalysts may bridge the knowledge of supported metals and traditional alcohol synthesis catalysts.
