ABSTRACT
We report on the synthesis of zinc vanadate nanostructures using electrochemistry assisted laser ablation in liquid (ECLAL) method for the first time. ECLAL was thought to be newly developed one-step approach for synthesis of simple polyoxometalates without catalyst and complex chemicals under the ambient environment. Scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) analysis were used to study the morphology and structure information of the prepared material. These results show that zinc vanadates are well assembled into 3D micro-nano flowers shape and each unit is actually composed of many ultrathin sheets with large specific surface area. Furthermore, we employ Fourier transform infrared spectroscopy (IR) and Raman scattering spectroscopy to reveal the molecular information of the as-synthesized products, and UV-vis spectrophotometer to study the optical absorption properties of the as-synthesized products. The MPMS test indicates that the Zn3(OH)2V2O7·2H2O nanostructures display the ferromagnetic properties at room or low temperature. Moreover, the physical and chemical mechanisms of the synthesis of the zinc vanadates are also pursued upon ECLAL.
