제목 Ni-doped A-site deficient (La,Sr)TiO3 with exsolved Ni nanoparticles as alternative anode material for SOFCs
초록  A-site deficient La-doped SrTiO3 (LST) is promising anode materials for SOFCs owing to high electronic conductivity and excellent phase stability. However, compared to Ni-based anodes, LST has much lower catalytic activity. Recently, Ni-doping strategy has emerged as an effective method to improve catalytic activity for perovskite materials. When Ni is doped into the lattice, Ni nanoparticles (NPs) are exsolved under reducing conditions and provide catalytic active sites on the electrode surface.
 In this work, we designed Ni-doped LST, LSTN as alternative anode material for SOFCs. LSTN with exsolved Ni NPs exhibited higher performance than non-doped LST. Our results demonstrated that LSTN with exsolved Ni NPs is a promising anode material for SOFC applications.
