Article Synopsis
- The lattice oxygen mechanism (LOM) enhances oxygen evolution reactions (OERs) by involving active lattice oxygen, making it important to maintain the stability of LOM materials.
- A heterostructure of Bi/BiCeOH is created through a simple electrochemical process, featuring under-coordinated oxygen atoms that increase electrochemical activity.
- The resulting anion exchange membrane water electrolyzer shows impressive performance with a low cell voltage of 1.79 V at a high current density and maintains stability over 100 hours with only a slight voltage increase.
Non-aqueous lithium-oxygen batteries (LOBs) have emerged as a promising candidate due to their high theoretical energy density and eco-friendly cathode reaction materials. However, LOBs still suffer from high overpotential and poor cycling stability resulting from difficulties in the decomposition of discharge reaction LiO products. Here, a 3D open network catalyst structure is proposed based on highly-thin and porous multi-metal oxide nanofibers (MMONFs) developed by a facile electrospinning approach coupled with a heat treatment process.
