Micro-nano heterogeneous oxides have received extensive attention due to their distinctive physicochemical properties. However, it is a challenge to prepare hierarchical structured metal oxide nanomaterials with abundant heterogeneous interfaces in a controllable way. In this work, the effective...

BiFeO 3 -BaTiO 3 system has a good application prospect in the field of high temperature lead-free piezoelectric ceramics because of the high Curie temperature and strong piezoelectric characteristics. In this work, the trace Mn 4+ -modified 0.7BiFeO 3 -0.3BaTiO 3 ceramics (0.7BF-0.3BT- x Mn)...

With respect to intermediate-temperature solid oxide fuel cells (IT-SOFCs), electrocatalytic activity of the cathodes dominates their output power. Herein A-site gadolinium-doped La0.33Ba0.62Gd0.05Co0.7Fe0.3O3-δ (LBGCF) perovskite is synthesized and systematically evaluated as the cathode for...
