Özet:
Recently, researchers have focused on multimetal oxide materials to meet energy requirements and to improve their properties, such as electrochemical and areas of usage. Multimetal oxide materials are widely used in batteries such as Li-ion and Ni-MH, in semiconductors, in water splitting studies, in fuel cells, and in catalyst studies. In this study, nickel hydroxide (alpha and beta form) was synthesized by using urea decomposition method. Co, Zn, Al, and Cu-doped Ni(OH)2 were also synthesized via same method. Here, optimization and cell (battery) studies were done to improve the nikel hydroxide capacity. C rate, binder effect, and electrolytic effect were discussed as well. In the study, BSCF, Ag-doped BSCF, and novel BSNF materials were synthesized by utilizing sol-gel method. Also, to determine their perovskite class, Goldschmidt tolerance factors were first calculated for BSCF, Ag-BSCF, and BSNF. It was found that, according to the Goldschmidt factor, all these materials were in the perovskite class. In the thesis, Cr, Co, Fe, Mn, and Ni nitrate salts were used to prepare printable inks. All printable inks were also optimized to print on a substrate. By using the printable inks, multimetal oxide materials were fabricated on the FTO glass, which offers hydrogen and oxygen from water. Last, PbVO3CI material was synthesized and characterized. We discussed various properties, such as semiconductor, electronic structure, dynamic stability (Born-phonon criteria), and perovskite class. The materials we discussed in the thesis, especially AgBSCF, BSNF, and PbVO3CI can be promising in solar cells, SOFCs, batteries, semiconductors, and electrocatalytic studies
