设计和合成用于在碱性环境中将水有效电化学转化为分子氢和将氢氧根离子有效电化学转化为氧的材料对于减少水-碱电解槽中的能量损失是至关重要的。在此，使用在析氢反应（HER）和析氧反应（OER）区域中具有不同化学计量和形态的3d-M氢（氧）氧化物，我们建立了这些反应的总体催化活性作为更基本的性质，描述符，OH-M2+ δ键强度（0
Design and synthesis of materials for efficient electrochemical transformation of water to molecular hydrogen and of hydroxyl ions to oxygen in alkaline environments is of paramount importance in reducing energy losses in water-alkali electrolysers. Here, using 3d-M hydr(oxy)oxides, with distinct stoichiometries and morphologies in the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) regions, we establish the overall catalytic activities for these reaction as a function of a more fundamental property, a descriptor, OH-M2+delta bond strength (0
