and magnetic properties have been investigated for various alkali metal clusters in zeolites [10,12–24]. Zeolites are thought to be one of the most ideal host matrices or containers of alkali metal nanoclusters. The advantages of the use of zeolite matrices are listed as follows. (1) The maximum size of the cluster

Zeolite is a silicabased volcanic ash (sandlike mineral) that forms over time. Zeolite is an alkaline mineral that is very porous and has a negative charge. Since most toxins, such as heavy metals, radiation, and pesticides, are positively charged, zeolite is pulled to the toxins, like a magnet, and sucks them up into its structure.
· Iron‐impregnated medium pore zeolite ZSM‐5 (pore opening of Å) is an efficient alyst for the conversion of synthesis gas (CO+H2) to high octane gasoline. Activity and selectivity of the ZSM‐5 (Fe) depends upon the manner in which Fe is impregnated on ZSM‐5. Magnetic and Mössbauer studies were conducted on alysts prepared by two methods: (a) ferric nitrate impregnation and ...

The 29 SiNMR measurements on several samples of potassium loaded zeolite LTA (K x /K 12 Al 12 Si 12 O 48 ), where x (1≦x≦7) is loaded potassium atoms per αcage, were carried out. It was found that NMR lineshape at K significantly depends on the x. These spectra were divided into different 3 types; diamagnetic phase for x≦2, magnetic ordered phase for 3≦x≦5, and paramagnetic ...
Zeolite is formed by silicaoxygen and aluminiumoxygen tetrahedra by sharing an oxygen atom, and the oxygen atoms form a ring, which is the basic unit of the zeolite Zeolite has been widely used in different reactions worked as alysts for a long time. The name "molecular sieves", is used to describe microporous zeolites due
