Phenomenologically, Pt-based nanowires, one of the most important nanostructures, have displayed high activity for oxygen reduction reaction (ORR); however, the fundamentally catalytic origin behind such high performance remains elusive and was implicitly ascribed to one-dimensional structure and/or low-index facets. Here, with molecular-level and operando spectroscopic evidence, we reveal that the polycrystalline platinum nanowires with enhanced ORR activity are closely correlated with structural defects including grain boundaries (GBs), atomic steps, and a few amorphous regions, which is previously neglected or simplified. The local micro-strain is induced by GBs and increases with misorientation angles of GBs. Despite the same coordination number between edge sites and atomic steps, the latter together with a few amorphous regions disturb interfacial water networks via preferably hydrogen bonding, which destabilizes ORR intermediates on terraces and presumably promotes proton transfer.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1016/j.apcatb.2022.122268", "subitem_relation_type_select": "DOI"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1873-3883", "subitem_source_identifier_type": "EISSN"}]}, "item_10001_version_type_20": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_71e4c1898caa6e32", "subitem_version_type": "SMUR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Xiao, Zhao", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takao, Shinobu", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yoshida, Yusuke", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kaneko, Takuma", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Gunji, Takao", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Higashi, Kotaro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Uruga, Tomoya", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Iwasawa, Yasuhiro", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2024-04-02"}], "download_preview_message": "", "file_order": 0, "filename": "APCATB-D-22-05462.pdf", "filesize": [{"value": "2.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 2400000.0, "url": {"url": "https://uec.repo.nii.ac.jp/record/2000173/files/APCATB-D-22-05462.pdf"}, "version_id": "a6d5879b-ea1f-4872-a014-5ac7460635c1"}, {"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2024-04-02"}], "download_preview_message": "", "file_order": 1, "filename": "Appendix-A_Supporting Information_SI-Xiao_Iwasawa.pdf", "filesize": [{"value": "2.8 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 2800000.0, "url": {"url": "https://uec.repo.nii.ac.jp/record/2000173/files/Appendix-A_Supporting Information_SI-Xiao_Iwasawa.pdf"}, "version_id": "bf46c5a3-2c55-40c1-9232-741992f2b7c1"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Roles of structural defects in polycrystalline platinum nanowires for enhanced oxygen reduction activity", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Roles of structural defects in polycrystalline platinum nanowires for enhanced oxygen reduction activity", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "13", "path": ["6"], "permalink_uri": "https://uec.repo.nii.ac.jp/records/2000173", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2024-04-02"}, "publish_date": "2024-04-02", "publish_status": "0", "recid": "2000173", "relation": {}, "relation_version_is_last": true, "title": ["Roles of structural defects in polycrystalline platinum nanowires for enhanced oxygen reduction activity"], "weko_shared_id": -1}
