1. INTRODUCTION
Zeolites are nanoporous crystalline alumino-silicates with
a rich variety of interesting properties and industrial ap-
plications.1
With over 140 zeolite framework topologies
synthetically available--each with its own range of com-
positions--zeolites offer size-, shape- and electrostatically-
selective adsorption, diffusion and reaction up to re-
markably high temperatures. Zeolites are widely used as
petroleum catalysts, desiccants, ion exchangers and filters,
environmentally safe detergents, and as molecular sieves
for separating chemical mixtures. It is safe to say that
zeolites offer a rich array of nanotechnologies.
The structural and chemical versatility offered by zeo-
