Abstract

Using electron- and X-ray-based characterization techniques, three paracrystalline structural motifs are shown to form at the surface of amorphized iridium oxide catalysts upon use for water electrolysis in acidic conditions. An iridium oxide catalyst containing only these paracrystalline structural motifs achieves enhanced performance, making more efficient use of its limited iridium content.

识别电解水用氧化铱催化剂表面的重组图案

利用基于电子和 X 射线的表征技术，在酸性条件下用于水电解时，非晶态氧化铱催化剂表面会形成三种副晶结构图案。仅含有这些副晶结构图案的氧化铱催化剂性能得到了提高，使其有限的铱含量得到了更有效的利用。
