Na Nuclear Spin-Lattice Relaxation in Dehydrated Zeolite NaY*
The spin-lattice relaxation time T\ of 2 , N a N M R in dehydrated zeolite NaY has been measured from 26 to 300 K. The magnetization recovery curve is not single-exponential at all measured temperatures and 1 increases in proportion to the square of temperature above 200 K. The result is analyzed with a theory of the Raman process based on covalency. The value of T\ is compared with that of NaX...
متن کاملDynamics of Water in Zeolite NaY(Br) Investigated by NMR
1. Introduction Zeolites are widely used in industry as molecular sieves, selective adsorbents, catalysts and ion exchangers (e.g. [1] and references therein). Therefore there is a great interest in studying the dynamics of guest molecules in such systems. Although vigorous research has been performed in the field, a complete understanding of the complex behaviour of guest molecules is still mi...
متن کاملXenon and krypton separation in a chromatographic column packed with granulated nano NaY zeolite
In order to investigate the gas separation ability of a column packed with nanozeolitic material, nano NaY zeolite was synthesized and granulated. These uniform granules packed in a chromatographic column were utilized for separation of Xe and Kr under various operating conditions. With regards to the response peaks obtained from trace injections of Xe and Kr into the column, the first and seco...
متن کاملA small paramagnetic platinum cluster in an NaY zeolite: characterization and hydrogen adsorption and desorption.
A well-defined cluster containing 12 equivalent platinum atoms was prepared by ion exchange of an NaY zeolite, followed by hydrogen reduction. It was characterized by electron paramagnetic resonance (EPR) spectroscopy, hyperfine sublevel correlation (HYSCORE), and theoretical calculations. Combing the results of the experiments with density functional calculations, the likely structure of this ...
متن کاملEncapsulation of Tetracarbonyl(trimethylstanny1)cobalt in NaY Zeolite: Reactivity and Alloy Cluster Formation
A bimetallic precursor route toward the encapsulation of subnanometer tin-transition metal alloy clusters in zeolites is presented. The intrazeolite chemistry and thermal stability of MesSnCo(CO)4 in NaY zeolite were studied with X-ray absorption spectroscopy (Sn, Co edge EXAFS) and in-situ FTIR/TPD-MS techniques. In the NaY host, the intact precursor is physically adsorbed from hexane solution...
