However, rational methodologies for designing self-repairing catalysts have not yet been established. Herein, hybrid cobalt hydroxide nanosheets (Co-ns), with a high deposition (repairing) rate, and β-FeOOH nanorods (Fe-nr), with high oxygen evolution reaction (OER) ability, are electrostatically self-assembled into composite catalysts. This strategy is developed to integrate multifunctionality in self-repairing catalysts. Positively charged Co-ns and negatively charged Fe-nr form uniform composites when dispersed in an electrolyte. These composites are electrochemically deposited on a nickel electrode by electrolysis at 800 mA cm−2. Co-ns form a conductive mesoporous assembly of CoOOH nanosheets as a support. Fe-nr are then distributed on the CoOOH nanosheets as active sites for the OER. Because of the high deposition rate of Co-ns, the amount of Fe-nr deposited increases 22 times compared to when Fe-nr is deposited alone, and the OER current density increases 14 times compared to that of Co-ns alone. The composite self-repair catalyst shows the highest activity and durability under an accelerated durability test (ADT), and its degradation rate decreases from 84 μV cycle−1 (Fe-nr only) to 60 μV cycle−1 (composite catalyst) under ADT conditions without repair.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley-VCH GmbH","subitem_publisher_language":"en"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1002/aesr.202400196","subitem_relation_type_select":"DOI"}}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Creative Commons Attribution 4.0 International","subitem_rights_language":"en","subitem_rights_resource":"https://creativecommons.org/licenses/by/4.0/"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2699-9412","subitem_source_identifier_type":"EISSN"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Department of Chemistry Applications and Life Science, Graduate School of Engineering Science, Yokohama National University","affiliationNameLang":"en"}]},{"affiliationNames":[{"affiliationName":"Advanced Chemical Energy Research Center, Institute of Advanced Sciences, Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Kuroda, Yoshiyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"0000-0001-6854-4432","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0001-6854-4432"},{"nameIdentifier":"50638640","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50638640"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Department of Chemistry Applications and Life Science, Graduate School of Engineering Science, Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Mizukoshi, Daiji","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Department of Chemistry Applications and Life Science, Graduate School of Engineering Science, Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Yadav, Vinay","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Kawasaki Heavy Industries Ltd.","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Taniguchi, Tatsuya","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Kawasaki Heavy Industries Ltd.","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Sasaki, Yuta","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"De Nora Permelec Ltd.","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Nishiki, Yoshinori","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"De Nora Permelec Ltd.","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Awaludin, Zaenal","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"De Nora Permelec Ltd.","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Kato, Akihiro","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Department of Chemistry Applications and Life Science, Graduate School of Engineering Science, Yokohama National University","affiliationNameLang":"en"}]},{"affiliationNames":[{"affiliationName":"Advanced Chemical Energy Research Center, Institute of Advanced Sciences, Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Mitsushima, Shigenori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70323938","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70323938"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-11-29"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2024-10-02"}],"filename":"Adv Energy and Sustain Res -
