摘要：

Aluminosilicates, gallosilicates, and indosilicates with the ZSM-5 type structure were prepared by the ''Atom-Planting method''. The introduction of metal cations into the framework of highly siliceous ZSM-5 zeolites was confirmed by IR and unit cell volume measurements. The acidic properties of these metallosilicates were examined by pyridine-IR and NH3-temperature programmed desorption spectroscopies. The increasing order of the acid strengths of the metallosilicates is indosilicate < gallosilicate < aluminosilicate.
