Abstract :
A series of Pt-exchanged molecular sieves was studied by X-ray absorption spectroscopy (XANES and EXAFS) in order to probe the effect of the structural and chemical characteristics of selected molecular sieves on the Pt particles. For each molecular sieve (LTL, MOR, and AFI) different preparation procedures (ion exchange, wet impregnation and vapor phase impregnation) were applied. For a particular molecular sieve the particle size increased in the order, ion exchange
