J. Heyrovsky Institute of Physical Chemistry

Introduction

The J. Heyrovsky Institute of Physical Chemistry is a centre of fundamental research in physical chemistry, electrochemistry and chemical physics. The Department of Structure and Dynamics in Catalysis (Z. Sobalik, B. Wichterlova) has a long-term experience in synthesis, modification and characterization of catalysts based on metallo-zeolites. The group specializes in analysis of the structure-performance relationship using multi-spectroscopic approaches under in situ conditions. It gained unique experience in analysis of the processes of incorporation of transition metal species into zeolites and characterization of the TM ion – guest molecule interactions using combination of experimental and theoretical techniques. The group was a project coordinator of the EU project AMMONORE GRD-2001-00595, and was involved in several EU, COST and US-CZ research projects and holds several industrial cooperative contracts. At present is a member of the network IDECAT.
