Preparation and characterization of SOFC cathodes made of SSC nanofibers

Effect of SSC Loading and Calcination Temperature on The Phase and Microstructure Formation of SSC-SDCC Cathode

“…It can be observed from X-ray diffractograms ( Fig.1-Fig.3) as pure Sm0.5Sr0.5CoO3−δ, SSC individually exhibited an equivalent with orthorhombic perovskite structure and in agreement with JCPDS of 53-0112 SSC commercial powder. As for pure Sm0.2Ce0.8O1.9, SDC carbonate, displayed with a cubic fluorite structure similarly to pure SDC lattice structure with equivalence as JCPDS75-0158 are clearly seen [9,12]. The carbonate phase from binary carbonate content (SDCC) revealed the crystallite peak of the SDC pure fluorite type structure an equivalence with pure SDC structure, as mention earlier.…”

“…Currently, mixed ionic and electronic conductors (MIEC), of samarium strontium cobaltite, Sm0.5 Sr0.5CoO3-δ (SSC) perovskite oxide has been revealed as a potential cathode material because of its higher ionic electronic conductivity properties. It also exhibited extraordinary electronic conductivity compared to that of barium strontium cobalt ferrite (BSCF) that reveals virtuous catalysis for oxygen reduction and is particularly compatible with the ceria carbonate based electrolytes [8][9]. According to previous researchers, SSC based composite cathode is normally used with other ionic conducting ceria based electrolyte, such as gadolinia doped ceria (GDC) and samarium doped ceria (SDC) [10][11].…”

A review of polymer nanofibres by electrospinning and their application in oil–water separation for cleaning up marine oil spills

“…Polymeric nanofibres are produced using various techniques, e.g., electrospinning (Chang et al, 2015), melt blowing (Hammonds et al, 2014), bicomponent spinning (Tijing et al, 2014), and forcespinning (Lu et al, 2015). Among these techniques, electrospinning is used widely to fabricate nanofibres using different materials such as ceramics, and metal.…”
