摘要：

Nuclear magnetic resonance investigation on Ge-containing ITQ-13 zeolites synthesized by the fluoride route indicates that Ge is preferentially incorporated at the double four-membered rings (D4R) cages. Meanwhile, as the Ge content increases, fewer fluoride ions are located into the D4Rs, and specially into the fused pair [415262] cages.
