摘要：

Gold can activate propane or influence titania such that a reaction occurs in which bidentate propoxy species are formed on the catalyst (see picture). In the absence of gold this reaction is not possible. This observation brings the understanding of this unique catalyst system one step further. © 2005 Wiley-VCH Verlag GmbH & Co. KCaA, Weinheim.
