Microwave assisted synthesis of ZnO Calthrop-like Nanostructures in Ionic-Liquid

摘要

ZnO Calthrop-like framework have been synthesized via a microwave assisted way by thermal decomposition of precursors in the ionic liquid 1-butyl-3-ethyl imidazolium tetrafluoroborate ([Beim]BF_4) aqueous solution. The structure of [Beim]BF_4 were analyzed by means of IR and 1HNMR, The as-samples were characterized by XRD, SEM and UV techniques. The results showed that the as-prepared ZnO have wurtzite structure. Nanorods have a diameter of 50 nm to 100 nm and lengths of about 3μm, and the ionic liquid [Beim]BF_4 can not only act as a reaction medium but also modify ZnO nanorods in the reaction. The growth mechanics of ZnO nano-structure was preliminary studied.
