Introduction to the Paul Scherrer Institute
The
Paul Scherrer Institute (PSI) is Switzerland's largest research institute for natural and engineering sciences. Established in 1988, PSI is renowned globally for its cutting-edge research in various scientific domains, including
catalysis. With its state-of-the-art facilities and interdisciplinary approach, PSI plays a pivotal role in advancing our understanding and application of catalytic processes.
Catalysis is a process that accelerates chemical reactions by using substances called catalysts. These catalysts are not consumed in the reaction and can be used repeatedly. Catalysis is crucial in numerous industrial processes, including the production of fuels, chemicals, and pharmaceuticals. It also has significant environmental implications, such as in the development of cleaner energy sources and pollution control.
PSI's Role in Catalysis Research
PSI is at the forefront of catalysis research, focusing on both fundamental and applied aspects. The institute's research aims to develop more efficient and sustainable catalytic processes. Some of the key areas of focus include:
1.
Heterogeneous Catalysis: PSI investigates solid catalysts and their interactions with gaseous or liquid reactants. This research is crucial for industrial applications like the
Haber-Bosch process for ammonia synthesis and the catalytic converters used in automotive exhaust systems.
2. Homogeneous Catalysis: PSI explores catalysts that are in the same phase as the reactants, often in solution. This type of catalysis is vital for fine chemical synthesis and pharmaceutical production.
3.
Electrocatalysis: This area focuses on catalytic processes that involve electron transfer, essential for energy conversion technologies like
fuel cells and
water splitting for hydrogen production.
Advanced Facilities and Techniques
PSI boasts some of the most advanced facilities globally for catalysis research. These include:
