A hydrophobicity study was realized for a series of siliceous and steamed BEA, HZSM-5 and HY zeolites. The hydrophobicity was assessed according to the Weitkamp method by performing water and toluene competitive adsorption experiments. The Weitkamp h

A new test in liquid phase using dodecen-1 isomerization as a model reaction was developed to characterize the weak reactivity of cationic zeolites. Thanks to it, the NaY weak activity can be characterized in conditions close to those of several indu

In situ CW EPR, diffuse reflectance UV-visible and Raman scattering spectroscopies were used to monitor the spontaneous ionization of naphthalene by direct exposure to thermally activated acid HZSM-5 zeolite (Hn(AlO2)n(SiO2)96-n). Calcination of the

Publikováno v: Angewandte Chemie International Edition. 38:1819-1822

Evidence of the photogenerated long-lived biphenyl radical and a trapped electron in the void space of aluminated nonacidic ZSM-5 zeolites has been obtained from the time-resolved UV/Vis absorption, Raman scattering, and EPR spectra. The restoration
