The pH of the synthesis solution was found to have a very strong effect on the pore structure, chemical composition, and morphology of the synthesized materials. Materials synthesized by impregnation of V and/or Ce and by the one-pot hydrothermal route at pH << 1.0 showed the characteristic ordered pore structure of SBA-15. However, the materials prepared by the one-pot synthesis route at pH 1.5 gave complex pore structures with bottleneck-shaped and/or slit-like interconnected pores. Activity tests in the selective oxidation of propane showed higher activities for the V-incorporated materials than for the materials containing Ce and V-Ce. Catalysts synthesized by impregnation gave higher propane conversions. However, the propylene selectivity values were higher with the catalysts prepared by the one-pot route. An increase in the temperature from 550 to 600 degrees C led to increases in both the conversion and the propylene selectivity with the V- and V-Ce-incorporated materials prepared by the one-pot procedure at pH 1.5. For the V-incorporated catalyst prepared by this route, the propane conversion and propylene selectivity were obtained as 40% and 62%, respectively, at a space time of 0.4 s.g.cm(-3) and a temperature of 600 degrees C.", "doi": "10.1021/ie901672b", "has_grant": false, "journal": { "issue": "15", "pages": "6790-6802", "title": "INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH", "volume": "49" }, "license": { "id": "cc-by" }, "publication_date": "2010-01-01", "relations": { "version": [ { "count": 1, "index": 0, "is_last": true, "last_child": { "pid_type": "recid", "pid_value": "24559" }, "parent": { "pid_type": "recid", "pid_value": "24558" } } ] }, "resource_type": { "subtype": "article", "title": "Dergi makalesi", "type": "publication" }, "title": "Effect of Synthesis Conditions on the Structure and Catalytic Performance of V- and Ce-Incorporated SBA-15-like Materials in Propane Selective Oxidation" }, "owners": [ 1 ], "revision": 1, "stats": { "downloads": 7.0, "unique_downloads": 7.0, "unique_views": 40.0, "version_downloads": 7.0, "version_unique_downloads": 7.0, "version_unique_views": 40.0, "version_views": 42.0, "version_volume": 1890.0, "views": 42.0, "volume": 1890.0 }, "updated": "2021-03-15T11:30:23.397136+00:00" }
