The effect of calcination atmosphere on structural properties of Y-doped SrTiO3 perovskite anode for SOFC prepared by solid-state reaction

Layered-perovskite oxides with in situ exsolved Co–Fe alloy nanoparticles as highly efficient electrodes for high-temperature carbon dioxide electrolysis

“…Perovskite-based oxides, such as SrFeO 3− δ , doped-SrTiO 3− δ and La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 3− δ , have been widely studied as alternative fuel electrode materials for solid oxide fuel/electrolysis cells (SOFCs/SOECs) because of their good stability. 11–16 Their catalytic activity, nevertheless, is not sufficient for practical applications. It was reported that active B-site cations, such as Ni, Co, and Fe, could exsolve from the perovskite-based oxide matrix to form metal nanoparticles on the surface upon thermal reduction or applying negative bias.…”

A review on the preparation of anode materials and anode films for solid oxide fuel cell applications

“…97 A Y-doped SrTiO 3 anode synthesized using the SSR approach showed high crystallinity degree with a large solubility limit for the Y dopant. 35 Moreover, the doping caused an increase in microstrain and reduced the lattice parameters and crystallite size. Plekhanov et al 34 synthesized Ni-La 0.95 Sr 0.05 ScO 3-δ anode and reported that the structure of the anode was stable, with minor expansion when the atmosphere was changed from air to H.…”

“…The synthesis method affects the microstructure, porosity, particle size distribution, particle shape, and TPB of the anode. 27 Some of the approaches that are used to synthesize anode materials including ball milling, [28][29][30][31][32] solid-state reaction (SSR) method, [33][34][35] template-based synthesis method, [36][37][38] and wet chemical methods (WCMs), such as sol-gel, 15,[39][40][41][42][43][44][45] co-precipitation, [46][47][48][49] hydrothermal and solvothermal methods, 48,50,51 and combustion method. [52][53][54][55][56][57][58] Various deposition methods were also discussed and categorized in several groups including physical deposition, [59][60][61][62][63][64][65][66] chemical deposition, [67][68][69] and colloidal deposition.…”

The Synthesis and Characterization of Sol-Gel-Derived SrTiO3-BiMnO3 Solid Solutions

“…Transition to the ferroelectric phase in this compound can be induced by different methods, including 16 O substitution by an 18 O isotope [21], cation substitution [22], or the application of intense terahertz electric field excitation [23]. The hydrothermal method [24], polymerized complex method [25], solid-state reaction [26], spray-drying [27], and molten salt [28] are a few of the synthetic approaches that have been previously employed for the synthesis of STO.…”
