Novel La1−xCaxTi1−yTayO3-δ perovskites with enhanced conductivity for solid oxide fuel cell electrodes

The novel La1−xCaxTi1−yTayO3-δ nano perovskites with high oxygen vacancies have been prepared for solid oxide fuel cells (SOFCs) by facile hydrothermal method. To enhance the oxygen vacancies, structural, thermal and chemical stability, the phase composition of the materials was varied with multiple...
