Magnetic field‐enhanced electrocatalytic activity has recently emerged as an effective strategy for electrocatalytic reactions. However, modulating the electrical behavior and spin ordering in real‐time using magnetic field during the electrocatalytic process remains challenging. Herein, based on the coexistence of room‐temperature ferromagnetic and magnetoresistance (MR) properties in La1−xSrxMnO...
Promoting the initially deficient but economical catalysts to high‐performing competitors is important for developing superior catalysts. Unlike traditional nano‐morphology construction methods, this work focuses on intrinsic catalytic activity enhancement via heteroatom doping strategies to induce lattice distortion and optimize spin‐dependent orbital interaction to alter charge transfer between...
It remains challenging to achieve further breakthroughs in the development of durable bifunctional air cathode electrocatalysts for increasing the cycling life of rechargeable Zn‐air battery (RZAB). Herein, d‐band gap narrowing strategy is proposed to significantly boost the electrocatalytic activity and stability of spinel Co3O4 for both oxygen reduction and evolution reactions. In situ Raman spectroscopy...
The application of magnetic fields in the oxygen reduction/evolution reaction (ORR/OER) testing for electrocatalysts has attracted increasing interest, but it is difficult to characterize on‐site surface reconstruction. Here, a strategy is developed for annealing‐treated FeCo2O4 nanofibers at a magnetic field of 2500 Oe, named FeCo2O4‐M, showing a right‐shifted half‐wave potential of 20 mV for the...
