Abstract
Zinc hydroxide fluoride (Zn(OH)F) with novel flower-like morphology has been prepared via a microwave-assisted ionic liquid route. The flower-like Zn(OH)F particle has six petals and every petal is composed of lots of acicular nano-structure. Nanoporous ZnO is obtained by thermal decomposition of as-prepared Zn(OH)F in air, and the flower-like morphology is well retained. In the process of synthesis, ionic liquid 1-Butyl-3-methylimidazolium tetrafluoroborate is used as both the reactant and the template.
Highlights
The conventional inorganic synthetic procedures usually demand long reaction time, high temperature, and toxic solvents
The obtained samples were characterized by X-ray diffraction (XRD) (Bruker D8 advance), field-emission scanning electron microscopy (FESEM) (LEO 1530), transmission electron microscopy (TEM) (JEOL JEM2100), and nitrogen adsorption–desorption analysis (Micromeritics ASAP2010)
The XRD pattern reveals that the main composition of the product is Zn(OH)F (JCPDS 32-1469) and a few impurities can be detected
Summary
The conventional inorganic synthetic procedures usually demand long reaction time, high temperature, and toxic solvents. Different from the traditional solvents, ionic liquids are potential green solvents with many advantages, such as negligible vapor pressure, low interface tension, supramolecular solvents, and microwave absorbing ability [1, 2]. Because of these excellent performances, ionic liquids can be the new ‘‘all in one’’ solvents, which are combination of solvent, template, and reactant [3]. For the first time, ionic liquid 1-Butyl-3methylimidazolium tetrafluoroborate ([Bmim]BF4) is used as the reactant and the template to synthesize novel flowerlike Zn(OH)F via an easy and fast microwave-assisted route. The obtained samples were characterized by X-ray diffraction (XRD) (Bruker D8 advance), field-emission scanning electron microscopy (FESEM) (LEO 1530), transmission electron microscopy (TEM) (JEOL JEM2100), and nitrogen adsorption–desorption analysis (Micromeritics ASAP2010)
