Reduction of the catalysts under the standardized condition (673 K, 15 min) showed that Pt catalysts supported on low surface area CeO2 (12.6 m2\u30fbg-1) gave reasonable ratios of adsorbed CO to total Pt. However, the CO/Pt ratio exceeded unity on high surface area CeO2 support (66.7 m2\u30fbg-1), suggesting adsorption of CO on the CeO2 surface. Reduction of the catalyst under milder conditions at 373 to 573 K for 15 min to 5 h gave constant CO/Pt ratio of 0.40 within a reasonable experimental error. The mean particle diameter estimated from this CO/Pt ratio on the assumption of spherical particles closely agreed with a volume-area mean diameter measured by TEM. It was concluded that the dispersion of Pt supported on CeO2 can be measured by lowering the reduction temperature to suppress the effect of the CeO2 support.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/14010"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u793e\u56e3\u6cd5\u4eba\u65e5\u672c\u77f3\u6cb9\u5b66\u4f1a"}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1346-8804", "subitem_source_identifier_type": "ISSN"}]}, "item_10_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u99d2\u4e95, \u614e\u4e00"}], "nameIdentifiers": [{"nameIdentifier": "38466", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Komai, Shin\u0027ichi"}], "nameIdentifiers": [{"nameIdentifier": "38467", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u77e2\u6fa4, \u7fa9\u8f1d"}], "nameIdentifiers": [{"nameIdentifier": "38468", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yazawa, Yoshiteru"}], "nameIdentifiers": [{"nameIdentifier": "38469", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u85a9\u6469, \u7be4"}], "nameIdentifiers": [{"nameIdentifier": "38470", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Satsuma, Atsushi"}], "nameIdentifiers": [{"nameIdentifier": "38471", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u670d\u90e8, \u5fe0"}], "nameIdentifiers": [{"nameIdentifier": "38472", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hattori, Tadashi"}], "nameIdentifiers": [{"nameIdentifier": "38473", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "32_Journal_of_the_japan_petroleum_institute_48_173-177.pdf", "filesize": [{"value": "182.7 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 182700.0, "url": {"label": "32_Journal_of_the_japan_petroleum_institute_48_173-177.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/12132/files/32_Journal_of_the_japan_petroleum_institute_48_173-177.pdf"}, "version_id": "17b945c9-ac6b-470e-95ff-d9cb9f7480f9"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Metal dispersion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Platinum catalyst", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ceria support", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Carbon monoxide adsorption", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Reduction condition", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Determination of Metal Dispersion of Pt/CeO2 Catalyst by CO-pulse Method", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Determination of Metal Dispersion of Pt/CeO2 Catalyst by CO-pulse Method"}]}, "item_type_id": "10", "owner": "1", "path": ["320/321/322"], "permalink_uri": "http://hdl.handle.net/2237/14010", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2010-08-17"}, "publish_date": "2010-08-17", "publish_status": "0", "recid": "12132", "relation": {}, "relation_version_is_last": true, "title": ["Determination of Metal Dispersion of Pt/CeO2 Catalyst by CO-pulse Method"], "weko_shared_id": null}
