Abstract
In the current study, we describe the synthesis and characterization of BaTiO3/Ba4Ti13O30 nanocomposite with aid of tetrabutyl titanate and Ba(NO3)2 as the starting reagents in the presence of water as the solvent by two step sol–gel method. This study aimed to investigate the effects of different surfactants and their concentrations such as glucose and lactose on the morphology and particle size of final products. Based on the SEM results, it was found that the size and morphology of the products could be greatly influenced by the aforementioned parameters. To the best of author knowledge, it is first report in synthesis of BaTiO3/Ba4Ti13O30 nanocomposite through the two step sol–gel method. Furthermore, to examine the solar cell application of as-synthesized BaTiO3/Ba4Ti13O30 nanocomposite, FTO/TiO2/BaTiO3/Ba4Ti13O30/Pt-FTO structures was created by deposited BaTiO3/Ba4Ti13O30 nanocomposite film on top of the TiO2 layer. The obtained nanocomposite with different morphologies and sizes was characterized by XRD, SEM, TEM, EDS, FT-IR, and DRS.
