Regulating the electronic structure of catalysts is most efficient strategy yet, despite its limitations, to improve their oxygen evolution efficiency. Instead only adjusting structure, here we utilize ferroelectric polarization accelerate reaction as well. This demonstrated on a multiferroic layered perovskite Bi5CoTi3O15 with in-situ grown BiCoO3. Thanks superimposed effects regulation and polarization, as-prepared electrocatalysts are more than benchmark IrO2 (with final 320 mV...

Single-phase materials with room temperature (RT) exchange bias (EB) are very important for future applications in spintronic devices, magnetic storage, and sensors. However, such rare because EB normally occurs ferromagnetic (FM)/antiferromagnetic (AFM) boundaries. In this work, RT was realized by breaking the homogeneous structure of long-period Aurivillius oxides through a simple Fe/Ti content modulation.

Tailoring the reciprocity between charge and spin degrees of freedom in perovskites is effective designing realizing novel spintronic functionalities. Recently, it has been proposed that this type quantum correlation can be intensively engineered via structure modulation, such as introducing protons into SrCoO3 SmNiO3. To end, we describe a new structure-modulating strategy F– substitution, e.g., perovskite oxyfluoride, SrCoO2.9−δF0.1, against hexagonal Sr2Co2O5. Co K-edge X-ray absorption...
