Real-world carbon surface morphology and metal-carbon interfaces are complex and interrelated and hard to control at a statistical level. Herein, we fabricated plasma-devised nanoneedles-glassy carbon (GC) from well-defined flat GC as model supports, on which Pt nanoparticles were anchored by arc plasma. The arc plasma deposited (APD)-Pt/flat-GC with a strong metal-support interface exhibited enhanced activity for the electrochemical oxygen reduction reaction (ORR) compared to chemically supported Pt/flat-GC and commercial Pt/C electrodes. The APD-Pt/nanoneedles-GC further promoted the ORR and showed a remarkable durability without significant deactivation after accelerated durability test cycles. The structural defects and compressive strain of Pt nanoparticles were induced by the plasma-devised metal-support contact, which may benefit the ORR activity of APD-Pt/nanoneedles-GC. The nanoneedles-GC support morphology may also improve oxygen gas transport at the nanoscale through modifying the hydrophobicity/hydrophilicity of the GC surface. These results on the devised Pt/C model electrodes reveal the highly enhanced activity and durability of the APD-Pt/nanoneedles-GC electrode by the doubly beneficial effects of a support nanoscale morphology and strong metal-support interface, which were characterized by the intimate combination of Pt/GC synthesis, electrochemical measurements, in situ XAFS, and HAADF-STEM. Our experimental findings provide necessary clues for the design and synthesis of active and durable fuel cell electrodes, metal-air batteries, and catalytic materials.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Chemical Society"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1021/acsaem.0c00528","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1021/acsaem.0c00528","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2020 American Chemical Society"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"25740962","subitem_source_identifier_type":"ISSN"}]},"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_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Zhao, Xiao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hamamura, Yutaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshida, Yusuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kaneko, Takuma","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gunji, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takao, Shinobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Higashi, Kotaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uruga, Tomoya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iwasawa, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-06-23"}],"displaytype":"detail","filename":"ACS Appl.
