The electrode demonstrates superior performance toward catalyzing oxygen evolution reaction (OER), affording a low overpotential of 0.23 V at the current density of 10 mA cm<jats:sup>−2</jats:sup>, high Faradaic efficiency of ≈98%, and stable operation for >60 h. Meanwhile, the electrode can dynamically change its color from gray silver to dark black with the OER happening, and the coloration/bleaching processes persist for at least 5000 cycles, rendering it a useful tool to monitor the catalytic process. Mechanism study reveals that the excellent structural properties of electrode such as 3D conductive framework, ultra thickness of N–NiFe LDH nanolayer (≈0.8 nm), and high N‐doping content (≈17.8%) make significant contribution to achieving enhanced catalytic performance, while N–NiFe LDH nanolayer on electrode is the main contributor to the stimuli‐responsive property with the reversible extraction/insertion of electrons from/into N–NiFe LDH leading to the coloration/bleaching processes. Potential application of this electrode has been further demonstrated by integrating it into a Zn–air battery device to identify the charging process during electrochemical cycling.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670319156776576","@type":"Researcher","foaf:name":[{"@value":"Sheng Chen"}],"jpcoar:affiliationName":[{"@value":"School of Chemical Engineering The University of Adelaide  Adelaide SA 5005 Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319156776577","@type":"Researcher","foaf:name":[{"@value":"Jingjing Duan"}],"jpcoar:affiliationName":[{"@value":"School of Chemical Engineering The University of Adelaide  Adelaide SA 5005 Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319156776578","@type":"Researcher","foaf:name":[{"@value":"Pengju Bian"}],"jpcoar:affiliationName":[{"@value":"School of Physics The University of Sydney  New South Wales 2006 Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319156776579","@type":"Researcher","foaf:name":[{"@value":"Youhong Tang"}],"jpcoar:affiliationName":[{"@value":"Centre for Nanoscale Science and Technology and Centre for Maritime Engineering, Control and Imaging Flinders University  Adelaide 5042 Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319156776704","@type":"Researcher","foaf:name":[{"@value":"Rongkun Zheng"}],"jpcoar:affiliationName":[{"@value":"School of Physics The University of Sydney  New South Wales 2006 Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1380579816006083840","@type":"Researcher","foaf:name":[{"@value":"Shi‐Zhang Qiao"}],"jpcoar:affiliationName":[{"@value":"School of Chemical Engineering The University of Adelaide  Adelaide SA 5005 Australia"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"16146832"},{"@type":"EISSN","@value":"16146840"}],"prism:publicationName":[{"@value":"Advanced Energy Materials"}],"dc:publisher":[{"@value":"Wiley"}],"prism:publicationDate":"2015-07-14","prism:volume":"5","prism:number":"18","prism:startingPage":"1500936"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Faenm.201500936"},{"@id":"https://advanced.onlinelibrary.wiley.com/doi/pdf/10.1002/aenm.201500936"}],"createdAt":"2015-07-14","modifiedAt":"2025-10-07","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360002216897889152","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Mesoporous Ni–Fe oxide multi-composite hollow nanocages for efficient electrocatalytic water oxidation reactions"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1002/aenm.201500936"},{"@type":"CROSSREF","@value":"10.1039/c6ta10094e_references_DOI_2ulFFimD0x4xdPmVfQpXon5yh8u"}]}
