XRD，XRF，BET，Mossbauer spectrum, TEM and 27AI 29SiMAS NMR is used to characterize the samples in material engineering. Samples of heterocrystalline synthesis show almost the same activity as those prepared by solid-state ion exchange. Both are superior to the samples by traditional methods. In NH3-SCR，Al-ZSM-5 exhibits a similar activity of deNOx to Cu-ZSM-5，while with C3H8 as reducing agent Cu-ZSM-5 is much better than Al-ZSM-5

AbstractIon exchanged ß“-aluminas display a number of interesting optical properties which suggest that the material is well suited for application as a solid state laser host. Small platelets of Nd3+ Ion exchanged β“-alumina exhibit laser action with gain coefficients many times greater than YAG. The versatility of the ion exchange process enables one to form a wide variety of compounds with different active ions and concentrations, thereby allowing the study of many different effects within a single host crystal.

The ion-exchanger Li0.6Zn1.2PO4of spinel type was prepared by a solid state reaction crystallization method. The extraction/insertion reaction with this material was investigated by X-ray, saturation capacity of exchange, and Kd measurement. The experimental results have proved that the acid-treated sample has a capacity of exchange 2.4mmol•g-1for Li+in the solution, The chemical analysis showed that the Li+extraction/insertion progressed mainly by ion-exchange mechanism and surface adsorption.
