Laboratory for Synchrotron Radiation and Femtochemistry

Mission

We develop and apply x-ray-based tools to solve scientific and technological questions in chemical research and related fields. Our world-leading instruments allow us to extract electronic and structural information from complex systems and to follow chemical processes from the initial electronic excitation to reaction mechanisms under operando conditions. We collaborate with Swiss and international scientists to advance academic and industrial research.

Scientific Highlights

Figure 1: Branching during the reaction mechanisms of the catalytic pyrolysis of guaiacol. The Bronsted acid site density is responsible, which reaction route is taken.

Unveiling the reaction mechanism shines light on the selectivity increase in catalytic processes

Increasing the selectivity of a chemical process through rational catalyst design is the Holy Grail of heterogeneous catalysis. Researchers at PSI and ETH Zürich showcase how revealing hidden steps in reaction pathways can steer processes towards preferred products, as demonstrated in a study focused on biomass valorization.

Tracking chemical bond changes with element selectivity and in real time

X-ray photoelectron spectroscopy probes the chemical environment in a molecule at a specific atomic site. Now the concept is extended with a site selective trigger to follow chemical bond changes as they occur on the femtosecond time scale.
