摘要：

A new microporous zinc silicate ZS-1 with Si to Zn mole ratio in the range 5.2 to 11.4 have been synthesized under hydrothermal condition using dibutyl amine as structure directing agent (SDA) in the presence of H3PO4 promoter. SDA can be removed by acid / ethanol extraction and the material show microporosity in N-2 sorption measurement. This material show very strong surface acidity and practically no loss of zinc on heating the acid extracted sample at 773 K for 6h.
