Synthesis of Zinc Hydroxyfluoride Nanofibers through an Ionic LiquidAssisted Microwave Irradiation Method

摘要

Zn(OH)F nanofibers were successfully synthesized fromZn5(OH)8(NO3)2.2H2O by microwave irradiation in the pres-ence of the ionic liquid [Tmim][BF4] (1,2,3-trimethylimid-azolium tetrafluoroborate). The structure and morphology ofthe resulting Zn(OH)F nanofibers were investigated by XRD,SEM, and XPS, and the results indicate that the Zn(OH)Ffibers are 80-200 nm in diameter and several micrometers in length. A hydrogen bonding π-π stacking mechanism isresponsible for the 1D feature of Zn(OH)F. This method maybe developed into a general way to synthesize other metalhydroxyfluoride nanostructures.
