Publikováno v: The Journal of Physical Chemistry C. 114:389-393

We demonstrate a simple method for the synthesis of nanoporous metal (Au, Pt, and Pd) rods by the galvanic exchange reaction using Ni as a sacrificial template. Nickel nanorods, prepared by electrodeposition inside porous alumina membrane, were conve

Publikováno v: Journal of Molecular Structure. :1-5

Acid sites on Co-, Cu- and PtZSM-5 as well as on Pt,Co- and Pt,CuZSM-5 samples were investigated by means of pyridine adsorption monitored by IR spectroscopy. After reduction in hydrogen a significant amount of acidity was observed on each zeolite sa

Fermi resonance of C1 chlorine compounds in the adsorbed phase of zeolites. An FTIR and MAS NMR spectroscopic study

Autor: I. Kiricsi, István Hannus, Zoltán Kónya, Janos B. Nagy

Publikováno v: Journal of Molecular Structure. :89-93

Fermi resonance was investigated for CH3Cl, COCl2, CO + Cl2, CCl4 and CCl2F2 adsorbed in NaYFAU zeolite. The extent of the resonance was measured by IR spectroscopy, while the mechanism of surface reaction was evidenced by MAS NMR spectroscopy.
