Abstract
A review; in this chapter, the emphasis moves to reactivity at metal ion sites in zeolites. One of the recent trends in the development of heterogeneous catalysts is connected with metal-contg. zeolites. Metal cations can be introduced into a zeolite at the synthesis stage as well as via various methods of zeolite modification (such as liq.- or solid-state ion-exchange technique, chem. vapor deposition). There are now a no. of unique catalysts (esp. MFI zeolites-based ones) showing high activity and selectivity in the diverse processes. Typical examples of such catalysts and processes are: Ti-contg. zeolites (hydrocarbon oxidn. by hydrogen peroxide); Fe zeolites (direct oxidn. of benzene into phenol by nitrous monoxide); Zn and Ga zeolite (dehydrogenation and aromatization of alkanes) and Cu, Fe, and Co zeolites (SCR of NOx).
