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"}],"filename":"APCATB-D-22-05462.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","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"}],"filename":"Appendix-A_Supporting Information_SI-Xiao_Iwasawa.pdf","filesize":[{"value":"2.8 MB"}],"format":"application/pdf","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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-02"},"publish_date":"2024-04-02","publish_status":"0","recid":"2000173","relation_version_is_last":true,"title":["Roles of structural defects in polycrystalline platinum nanowires for enhanced oxygen reduction activity"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2024-04-02T04:32:09.295384+00:00"}
