摘要

我们探索了使用具有层次化三维海胆状形貌的铁基阳极材料(α-赤铁矿)作为OER催化剂的可能性。电极是通过脉冲激光沉积,然后热退火导致分层三维海胆样形貌制备的。采用微罗曼光谱和扫描电镜研究了沉积参数对催化剂相和形貌的影响,采用伏安法和塔菲尔分析法测定了电极参数。我们观察到该材料对OER具有高度电活性,其性能与基于贵金属的最先进催化剂的性能一致。

Investigation of nanostructured iron oxides as anodic material for water splitting
We explore the possibility of using an iron-based anodic material (α-hematite) synthesized with a hierarchical 3D urchin-like morphology, as an OER catalyst. The electrodes are prepared by pulsed laser deposition followed by thermal annealing leading to the hierarchical 3D urchin-like morphology. The effect of the deposition parameter on the catalyst phase and morphology are investigated by microRaman spectroscopy and scanning electron microscopy, while the electrode metrics are determined by voltammetric methods and Tafel analysis. We observe that the material is highly electroactive towards the OER, with performance in-line with that of noble-metal based state-of-the-art catalysts.
