| Abstract: | AlPO-cristobalite was prepared at low temperature of 80 °C for 30 min in the bmim]Br ionic liquid. The effects of reaction conditions, such as the amount of organic amine and HF acid, the P/Al ratio, and reaction time, were investigated in detail in the ionothermal synthesis. Powder X-ray diffraction and high-resolution solid-state NMR show that the resultant sample is α-AlPO-cristobalite, and most of the Al and P species are located on the framework and connected by Al–O–P tetrahedron. |
