摘要

这张封面图片说明了在IrO2/BaO2催化剂上发生的析氧反应（OER）。层状结构突出了由于BaO2-IrO2相互作用而增强的电子转移和氧活性的来源，提高了在宽pH范围内的稳定性和效率。该研究表明，加入Ba氧化物可以优化OER性能，为开发经济高效的iro2基水分解电催化剂提供了有价值的见解。更多信息可以在Anthony P. O 'Mullane及其同事的研究文章中找到（DOI: 10.1002/celc.202400611）。

Cover Feature: Enhancing the Activity and Stability of IrO2 for the Oxygen Evolution Reaction over a Wide pH Range using Electrodeposited BaO2 (ChemElectroChem 13/2025)

This cover image illustrates the oxygen evolution reaction (OER) occurring on a IrO₂/BaO₂ catalyst. The layered structure highlights the origin of the enhanced electron transfer and oxygen activity due to BaO₂-IrO₂ interactions, improving stability and efficiency over a wide pH range. This study suggests that incorporating Ba oxides can optimize OER performance, offering valuable insights into developing cost-effective and efficient IrO₂-based electrocatalysts for water splitting. More information can be found in the Research Article by Anthony P. O’Mullane and co-workers (DOI: 10.1002/celc.202400611).
