Probing the Structure-Activity-Stability Relationship of High Performance Hollow IrCu Aerogel Catalyst for the Oxygen Evolution Reaction Usi

This experiment aims at elucidating the complex structure-activity-stability relationship driving the high performance of hollow iridium-copper (IrCu) aerogel catalyst for the oxygen evolution reaction (OER) at proton exchange water electrolyzer (PEMWE) anode. The proposal relies on the use of high energy X-ray scattering measurements in operando conditions, using a recently built X-ray transparent PEMWE cell and its test station apparatus available at the ID31 beamline of the ESRF.

本实验旨在阐明驱动质子交换膜水电解槽（proton exchange water electrolyzer, PEMWE）阳极用空心铱铜（iridium-copper, IrCu）气凝胶催化剂实现高性能表现的复杂结构-活性-稳定性关系。本研究方案依托欧洲同步辐射光源（European Synchrotron Radiation Facility, ESRF）ID31光束线处新近搭建的X射线透明型PEMWE电解池及其配套测试站装置，在原位（operando）条件下开展高能X射线散射测量。
