The aim of this proposal is the accurate prediction of chemical kinetics of catalytic reactions taking place in nanoporous materials from first principles. Two types of industrially important nanoporous materials are considered: zeotype materials including the standard alumino-silicates but also related alumino-phosphates and the fairly new Metal Organic Frameworks(MOFs). This class of materials in which organic and inorganic moieties are linked, have astonished the zeolite community by their giant pores and huge surface area.
