The Pt–Ni nanoparticle/HPCS catalyst synthesized in the presence of dpa exhibited remarkable electrochemical performance in the ORR showing a high mass activity of 3.25 ± 0.14 A mg^−1Pt at 0.9 VRHE (13.5-fold higher relative to a commercial Pt/C catalyst), a large electrochemical surface area of 105 ± 8 m^2 g^−1 Pt, and high durability. After 60 000 cycles of accelerated durability testing, the mass activity was still 12.3 times higher than that of the commercial Pt/C catalyst.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Royal Society of Chemistry","subitem_publisher_language":"en"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1039/D1DT00647A","subitem_relation_type_select":"DOI"}}]},"item_9_source_id_7":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"1477-9226","subitem_source_identifier_type":"PISSN"}]},"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":[{"creatorNames":[{"creatorName":"Wan, Xian-Kai","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Samjeské, Gabor","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Matsui, Hirosuke","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Chen, Chaoqi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Muratsugu, Satoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Tada, Mizuki","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-05-28"}],"displaytype":"detail","filename":"DT_ART_02_2021_000647_Wan-HPCS-no_highlighting.pdf","filesize":[{"value":"12.8 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/2001626/files/DT_ART_02_2021_000647_Wan-HPCS-no_highlighting.pdf"},"version_id":"cb1188cb-385c-4bee-99e8-9a8bc346bc39"}]},"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":"Ultrafine Pt–Ni nanoparticles in hollow porous carbon spheres for remarkable oxygen reduction reaction catalysis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ultrafine Pt–Ni nanoparticles in hollow porous carbon spheres for remarkable oxygen reduction reaction catalysis","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"17","path":["1919"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-11-16"},"publish_date":"2021-11-16","publish_status":"0","recid":"2001626","relation_version_is_last":true,"title":["Ultrafine Pt–Ni nanoparticles in hollow porous carbon spheres for remarkable oxygen reduction reaction catalysis"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-01-16T05:09:20.580930+00:00"}
