摘要：

In situ Al-27 NMR experiments under hydrothermal and room temperature conditions demonstrate that aluminum monomers are the species controlling the Al-13 Keggin epsilon conversion into A1(30). New Al-27 NMR signatures of Keggin-type aluminum polycation are observed in solution. A chemical pathway is proposed to explain the isomerization process. (C) 2003 Elsevier B.V. All rights reserved.
