Popis: | A1TUD-1, a new mesoporous, Brønsted acidic aluminosilicate with ideal characteristics for catalyst immobilization was used for the noncovalent anchoring of hydride tungsten complex [WH2(η2-OOCCH3) (Ph2PCH2CH2PPh2)2 ][BPh4]. The immobilization was carried out by an adsorption process in liquid phase. The new materials were characterized by several techniques: spectroscopic methods (ICP-AES, FT-IR and UV/Vis), X-ray techniques (XPS and XRD), isothermal nitrogen adsorption and elemental analysis. |
