It is our pleasure to invite you to participate in the "Workshop on Water in Zeolites".

Scope
An international workshop is being planned with the objective of bringing together world-known experts from the field of heterogeneous catalysis to discuss fundamental aspects about the interaction of liquid water in zeolite catalysts. This is a topic of profound consequences in several catalytic processes for chemical, petrochemical, and oil refining industries.

The proposed format for the workshop is two full days of talks, round tables, and discussions. Maybe late afternoon of the first day will be used for 2 invited lectures. The preliminary sessions will be as follows (tentative):
1. Water during zeolite synthesis and post-synthesis treatments
2. Solvent effects in liquid-phase reactions in zeolites
3. Water-assisted reactions
4. Theoretical aspects of the role of water in reaction

It is well-known that water exhibits unique characteristics associated with its polar covalent bonds. The two electron pairs in the O–H bonds of the H2O molecule are pulled close to the O atom, which acquires a partial negative charge, while both H atoms take on a partial positive charge, resulting in a large dipole moment. Thus, a water molecule has the ability to attract other water molecules through so-called H-bonds. This electrostatic attraction accounts for the high boiling point and heat capacity of water, as well as its strong cohesive and adhesive forces. Its high polarity makes water an excellent solvent for many substances, such as ionic salts (NaCl) and other polar substance (alcohols and acids). In recent years, influence of water on the stability, catalytic activity and selectivity of zeolitic materials has attracted attention of researchers.
These aspects include the study of water effects on:
(a) stability of zeolitic materials;
(b) reactant solubility and mass transport rates;
(c) stabilization of reactants, products, and transitions states;
(d) entropy and enthalpy changes in confined nanospaces;
(e) remote bond polarization; and
(f) H-shuttling.
