Bu çalışmada, nikel(II)nitrat hekzahidrat (Ni(NO3)26H2O), amonyum metavanadat (NH4VO3) ve sodyum hidroksitin (NaOH) sulu ortamdaki reaksiyonundan amorf ve nanoyapılı yeni bir nikel vanadyum oksit hidroksit hidrat (Ni3(OH)2V2O7.3H2O) bileşiği sentezlendi. X-ışınları toz kırınımı (XRD) tekniği ile bileşiğin amorf yapıda olduğu belirlendi. Bileşiğin kimyasal yapı formülü X-ışınları floresans (XRF) tekniği, termogrovimetri (TG) ve Fourier transform infrared spektroskopisi (FTIR) yardımıyla aydınlatıldı. Molekül yapısındaki su (H2O), hidroksil (OH-) ve pirovanadat fonksiyonel gruplarının olduğu FTIR ve TG verilerinden bulundu. Ayrıca taramalı elektron mikroskobu (SEM) kullanılarak elde edilen bileşiğin morfolojisi incelendi

Synthesis and Structural Characterization of a New Amorphous and Nanostructured Ni3(OH)2V2O7.3H2O Compound

Öz

In this study, a amorphous and nanostructured nickel vanadium oxide hydroxide hydrate compound (Ni3(OH)2V2O7.3H2O) was synthesized by the reaction of nickel (II) nitrate hexahydrate (Ni(NO)6HO) and ammonium metavanadate (NH4VO3) with sodium hydroxide (NaOH) in aqueous medium. The compound was determined to be amorphous by X-ray powder diffraction (XRD) technique. Chemical structural formula of the compound was illuminated by means of X-ray fluorescence (XRF) method, thermogravimetry (TG) and Fourier transform infrared spectroscopy (FTIR). The presence of aqua (H2O), hydroxide (OH-) and pyrovanadat functional groups in molecule was found by FTIR and TG data. Furthermore, the morphology of the compound was examined by using scanning electron microscopy (SEM)
