The order of hydrogenation activity is Pt>Pd>Ru, Rh in scCO<jats:sub>2</jats:sub> and in ethanol. The effectiveness of the support is C>Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>, SiO<jats:sub>2</jats:sub> for either Pt or Pd in scCO<jats:sub>2</jats:sub>. For all the catalysts, higher selectivity to aniline has been obtained in scCO<jats:sub>2</jats:sub> compared with ethanol. Hydrogenation of nitrobenzene catalyzed with Pd/C and Pt/C catalysts was successfully conducted in scCO<jats:sub>2</jats:sub> with a 100% yield to aniline at a lower reaction temperature of 35 °C. The product aniline (organic phase) can be easily separated from the side‐product water (aqueous phase), solvent (scCO<jats:sub>2</jats:sub>), and catalyst (solid) by a simple phase separation process. The hydrogenation of NB is a structure‐sensitive reaction in ethanol as well as in scCO<jats:sub>2</jats:sub> except for a few Pt/C catalysts in which the degree of metal dispersion is small (<0.08).</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388844579021956","@type":"Researcher","foaf:name":[{"@value":"Fengyu Zhao"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844579021954","@type":"Researcher","foaf:name":[{"@value":"Rong Zhang"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844579021955","@type":"Researcher","foaf:name":[{"@value":"Maya Chatterjee"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844579021952","@type":"Researcher","foaf:name":[{"@value":"Yutaka Ikushima"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844579021953","@type":"Researcher","foaf:name":[{"@value":"Masahiko Arai"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"16154150"},{"@type":"EISSN","@value":"16154169"}],"prism:publicationName":[{"@value":"Advanced Synthesis & Catalysis"}],"dc:publisher":[{"@value":"Wiley"}],"prism:publicationDate":"2004-05","prism:volume":"346","prism:number":"6","prism:startingPage":"661","prism:endingPage":"668"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fadsc.200303230"},{"@id":"https://advanced.onlinelibrary.wiley.com/doi/pdf/10.1002/adsc.200303230"}],"createdAt":"2004-06-09","modifiedAt":"2025-10-06","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004232515166720","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Theoretical study on interaction between CO2 and carbonyl compounds: Influence of CO2 on infrared spectroscopy and activity of C O"}]},{"@id":"https://cir.nii.ac.jp/crid/1360283690971652480","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Selective hydrogenation of chloronitrobenzene to chloroaniline in supercritical carbon dioxide over Ni/TiO2: Significance of molecular interactions"}]},{"@id":"https://cir.nii.ac.jp/crid/1360846641601884416","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Hydrogenation of Nitrostyrene with a Pt/TiO<sub>2</sub> Catalyst in CO<sub>2</sub>-Dissolved Expanded Polar and Nonpolar Organic Liquids: Their Macroscopic and Microscopic Features"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848657445317248","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Selective hydrogenation of nitrostyrene to aminostyrene over Pt/TiO2 catalysts: Effects of pressurized carbon dioxide and catalyst preparation conditions"}]},{"@id":"https://cir.nii.ac.jp/crid/2050307417130045568","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Rh-PVP catalyzed reductive amination of phenols by ammonia or amines to cyclohexylamines under solvent-free conditions"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1002/adsc.200303230"},{"@type":"OPENAIRE","@value":"doi_dedup___::dad3ac9220fc57d2deb28b094cf30930"},{"@type":"CROSSREF","@value":"10.1021/jp1105339_references_DOI_OQ43xoNcp3PYRuAkqfehM9TRIOC"},{"@type":"CROSSREF","@value":"10.1246/cl.210574_references_DOI_OQ43xoNcp3PYRuAkqfehM9TRIOC"},{"@type":"CROSSREF","@value":"10.1016/j.supflu.2011.02.016_references_DOI_OQ43xoNcp3PYRuAkqfehM9TRIOC"},{"@type":"CROSSREF","@value":"10.1016/j.jcat.2009.10.024_references_DOI_OQ43xoNcp3PYRuAkqfehM9TRIOC"},{"@type":"CROSSREF","@value":"10.1016/j.supflu.2010.03.002_references_DOI_OQ43xoNcp3PYRuAkqfehM9TRIOC"}]}
