Abstract:
Nano sized bimetallic oxide materials have been extensively studied worldwide because of their unique properties such as electrical conductivity, magnetic property and superior mechanical properties. The exercise objects the synthesis, characterization and studies like thermal and electrochemical study of the barium cerate (BaCeO۳). The facial approach to preparing well dispersed nanocrystals of (BaCeO۳) was prepared by oxalate precursor method. Barium oxalate and cerium oxalate precursors were prepared by direct dispersion of barium and cerium salt into oxalic acid solution separately. These precursors are undertaken for self-propagating combustion reaction under the influence of polyvinyl alcohol (PVA) fuel in the weight ration ۱:۱:۵ to form BaCeO۳ as required product. X-Ray diffraction (XRD) tool which is used to study the structural confirmation of prepared bimetallic oxide nanomaterials sample. The presence of a ۱۰۰% peak (۱۱۰) along with other reflections in the pattern confirms the sample. Morphological study of the sample was carried out by scanning electron microscope (SEM) tool. Bonding nature of the sample was well studied by Fourier transfer infrared (FT-IR) instrumentation. Metal confirmation in the prepared sample was identified by EDX analysis. Absorption variation was well analyzed by UV-Vis spectroscopy. Maximum absorption band at ۴۲۵ nm signifies the sample phase. Raman spectroscopic (RS) study was undertaken to view its structural organization. Dynamic light scattering (DLS) study was implemented to know the size of the sample. Cyclic voltammetry (CV) and thermal gravimetric analysis (TGA) studies are also experimented to know the electrolytic and thermal behavior of the barium cerate sample. Complete decomposition of the sample takes place at ۷۷۹.۴۱oC records thermal stability.
