摘要
The parent clays laponite (Lap) and K10-montmorillonite (K10) and those functionalised with (3-aminopropyl)triethoxysilane (APTES) were used as supports to immobilise vanadyl(IV) acetylacetonate ([VO(acac)2]). All the materials were characterised by elemental analysis, XRD, TG-DSC, nitrogen adsorption isotherms at −196 °C and IR spectroscopy. The K10-based materials were also characterised by XPS.
