Laboratory for Catalysis and Sustainable ChemistryTwo of the grand challenges of the 21st century are energy and sustainability. Within the Laboratory for Catalysis and Sustainable Chemistry, we combine synthetic chemistry with development and application of new (synchrotron-based) characterization tools to contribute to solving these challenges. Catalysis plays an essential role to energy conversion and storage as well as to achieving sustainable chemicals conversion.
An important part of our research therefore focuses on providing understanding of a functioning catalyst with the ultimate aim to be able to design better catalytic processes. This reflects the general research theme within the laboratory, which is to provide understanding of a functioning respectively functional material. The laboratory is in particular strong in the development and application of in situ / operando time- and space-resolved measurements. For that, we maintain strong links to the synchrotron. We apply methods based on X-ray absorption and emission and X-ray photoemission spectroscopies, in addition to ptychographic imaging. High space-resolution is achieved in both the hard and soft X-ray regimes and diffractive and spectroscopic imaging is explored.

In oil extraction sites, gaseous methane is simply burned, even though it could actually be a useful precursor material for fuels and products of the chemical industry. One way to make methane usable is to convert it to methanol. Researchers at the Paul Scherrer Institute PSI and ETH Zurich have now developed a new chemical process that allows this conversion in an efficient and inexpensive way.
Eighty percent of all products of the chemical industry are manufactured with catalytic processes. Catalysis is also indispensable in energy conversion and treatment of exhaust gases. Industry is always testing new substances and arrangements that could lead to new and better catalytic processes. Researchers of the Paul Scherrer Institute PSI in Villigen and ETH Zurich have now developed a method for improving the precision of such experiments, which may speed up the search for optimal solutions.
