The J. Heyrovsky Institute of Physical Chemistry, Academy of Sciences of the Czech Republic, is a centre of fundamental research in physical chemistry, electrochemistry and chemical physics. The research work is characterized by many cross-links both within the Institute and also with other institutions in Europe, the U.S.A., Japan and other parts of the world. Much of the scientific work is concerned with fundamental research, but several groups, in particular in catalysis and electrochemistry, are also making contributions in more applied aspects. Besides the research activities the Institute is strongly involved in training of both undergraduate and graduate students, supervising their diploma and Ph.D. theses, and in teaching at universities.

Research interest of the Department of Synthesis and Catalysis, which is a member of ShaleX consortium is synthesis and characterization of zeolites and mesoporous molecular sieves and their application in adsorption and catalysis centered on petrochemical applications and synthesis of fine chemicals. The main task is to understand the general relationship among the structure of molecular sieve catalysts, structure and properties of catalytically active sites and conversion and selectivity in transformations of aromatic hydrocarbons, acylation reactions, oxidations with hydrogen peroxide, metathesis of olefins and unsaturated esters or ethers, and reactions leading to formations of new C-C bonds.

The research directions are:

Synthesis of zeolites, zeotypes, mesoporous molecular sieves and hierarchic materials combining micro and meso porosity

  • synthesis of different structural types of zeolites and mesoporous materials
  • synthesis of layered materials and their transformations to zeolites
  • new approaches to the synthesis of organized mesoporous aluminas
  • applications of novel structure-directing agents for the zeolite synthesis
  • isomorphous substitution
  • application of microwave irradiation to the synthesis of molecular sieves
  • novel approaches to the synthesis of hierarchic materials

New zeolite synthesized in the Department (2012)

Adsorption of carbon dioxide, hydrogen and organic vapours on advanced molecular sieves

  • tailored synthesis of zeolites for adsorption of carbon dioxide
  • synthesis of mesoporous molecular sieves for adsorption of carbon dioxide and organic vapours
  • grafting of organic adsorption sites on the surface of mesoporous materials and delaminated zeolites

Catalytic application of zeolites, mesoporous molecular sieves and hierarchic materials

  • alkylations, isomerization, disproportionations and transalkylations of alkyl and dialkyl aromatic hydrocarbons
  • acylatrions of aromatics and their derivatives for fine chemical products and intermediates
  • metathesis of 1-olefins and unsaturated esters and ethers
  • oxidation reactions with hydrogen peroxide (Baeyer-Villiger reaction, Meerwien-Ponndorf-Verley reduction)
  • C-C coupling reactions (Heck reaction, Suzuki reaction, Sonogashira reaction)
