Ionothermal Synthesis and Structure Analysis of an Open-Framework Zirconium Phosphate with a High CO2/CH4 Adsorption Ratio

摘要

Zirconium phosphate materials have been investigated extensively because of their potential for application in the fields of ion-exchange, catalysis, photochemistry, and biotechnology. Most studies of these materials have focused on the two layer compounds α-Zr(HPO4)2H2O and γ-ZrPO4-(H2PO4)·2H2O and their derivatives, which are obtained by post-synthesis processing techniques (for example ion-exchange, intercalation, or grafting). The main reason most other zirconium phosphate materials have been neglected can probably be attributed to their poor thermostability.
