Facile synthesis of pure phase γ-AlOOH and γ-Al 2 O 3 nanofibers in a recoverable ionic liquid via a low temperature route
Mesoporous γ-AlOOH and γ-Al 2 O 3 with fibrous morphology were successfully synthesized by an ionic liquid ([OMim]Br) assisted low temperature precipitation method using aluminum nitrate and ammonia as aluminum source and precipitant, respectively. The samples were characterized by XRD, TG, FT-IR, T...
