For 70 years now we have been dedicated to the research of catalysis. Initially, it all started with research into the production of artificial butter in the post-war period. Today, the Leibniz Institute for Catalysis (LIKAT Rostock) is one of the largest publicly funded catalysis institutes in Europe with approx. 300 employees and guests and occupies a position at the interface of fundamentals and applications. Thus, we define our focus in the field of application-oriented basic research and promote industrial implementation. Concretely, this means that each year the scientists at the institute transfer at least two catalysts or catalytic processes to the industrial pilot scale. The classical boundaries between homogeneous and heterogeneous catalysis are consistently dismantled at the LIKAT, in favour of a comprehensive, materially and methodologically oriented science. In addition, the interdisciplinary inter-action of inorganic, organic and technical chemistry, nano-sciences, physical chemistry and process engineering plays an important role.
