Ultrasmall Manganese Nanospinels Produced via an Alcohol Reduction Method and Their Electrocatalytic Oxygen Evolution Reactivity.

ABSTRACT: Green hydrogen production via electrochemical water splitting extensively demands the development of cost-effective and highly efficient electrocatalysts for the anodic oxygen evolution reaction (OER). Nanosized spinel nanoparticles (nanospinels) are potential candidates as electrocatalysts for the OER because of their very high specific surface areas. This work systematically investigated the influence of the A-site metals in the Mn-based nanospinels, i.e., LiMn₂O₄, MgMn₂O₄, ZnMn₂O₄, NiMn₂O₄, CuMn₂O₄, and CoMn₂O₄. Evaluation of their OER activities then indicated that higher OER activities for NiMn₂O₄ and CoMn₂O₄ th
