Abstract
Keggin ion-pillared buserite was prepared by ion-exchanging the hexylammonium ion-expanded buserite with Keggin ions, [Al13O4(OH)24(H2O)12]7+. The starting material was synthetic Na-buserite, which is a layered manganese oxide of composition Na4Mn14O26 xH2O. The thermal and redox properties of this oxide and its pillared derivative were compared in O2, N2 and H2 environments using TG, DSC and XRD. The results indicated an improvement in thermal stability of pillared compound relative to Na-buserite in all gaseous environments. By using these compounds in catalysing the oxidation of ethane, it was found that they were very active for complete oxidation. © 1993 John Wiley & Sons, Limited and Akadémiai Kiadó.
