The cyclotrimerization of acetylene on NiY zeolites, containing 10, 14 and 19 Ni2+ ions/unit cell treated at 200 and 600 °C, has been investigated by means of X-ray diffraction analysis, ir and EPR spectroscopies. It has been shown that this reactio

Location and dispersion of platinum in reduced PtY zeolites were studied by X-ray diffraction, small angle X-ray scattering and chemisorption. In the case of a 300 °C activation most of the Pt2+ ions are found in supercages. On reducing at 300 °C,

13C and 1H NMR spectra of cyclopropane on various supported platinum catalysts were obtained. They showed that cyclopropane was specifically adsorbed on platinum and that the cyclic character of the molecule was preserved. The NMR spectra were interp

Bimetallic PtMoY catalysts have been prepared by adsorption and decomposition of Mo(CO)6 in a Y-type zeolite containing 10-A Pt particles trapped in the zeolite cages. Part of the Mo atoms are deposited onto the Pt particles which produces a weak inc
