For the former sample, the state of dispersion of Pd on TiO2 changed during the loading of Au, resulting in the formation of small Au-Pd alloy particles and thus changing the electronic properties of Pd species. The electronic properties of Pd on Pd/Au/TiO2_100 were not so different from those of monometallic Pd/TiO2_100. Moreover the nanocrystalline TiO2 materials (9 and 15 nm) were synthesized by the solvothermal method and employed as the supports for preparation of bimetallic Au/Pd/TiO2 catalysts. The Pd metal and/or Pd-Au alloy formed on the TiO2_9 (\u0026lt; 1 nm) were smaller than on TiO2_15 (2-3 nm) and on TiO2_100 (4-10 nm). All the catalysts were selective to 1-heptene (\u0026gt; 95%) until close to the complete conversion of 1-hetyne. However, the selectivity of 1-heptene drastically decreased to 0% (which was further hydrogenated to heptane) in 120 minute for the Au/Pd/TiO2_100 while it still remained \u0026gt; 40% for the Au/Pd/TiO2_9, Au/Pd/TiO2_15 and the monometallic Pd/TiO2 catalyst.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"http://doi.nrct.go.th/?page=resolve_doi\u0026resolve_doi=10.14457/CU.the.2013.1030","contentUrl":[],"metadataVersion":1,"schemaVersion":"http://datacite.org/schema/kernel-3","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":0,"citationCount":0,"citationsOverTime":[],"partCount":0,"partOfCount":0,"versionCount":0,"versionOfCount":0,"created":"2019-06-06T09:25:34.000Z","registered":"2019-06-06T09:25:34.000Z","published":"2013","updated":"2020-10-10T16:44:03.000Z"},"relationships":{"client":{"data":{"id":"nrct.db1","type":"clients"}},"provider":{"data":{"id":"wyth","type":"providers"}},"media":{"data":{"id":"10.14457/cu.the.2013.1030","type":"media"}},"references":{"data":[]},"citations":{"data":[]},"parts":{"data":[]},"partOf":{"data":[]},"versions":{"data":[]},"versionOf":{"data":[]}}}}
