Transient Technique for Identification of True Reaction Intermediates: Hydroperoxide Species in Propylene Epoxidation on Gold/Titanosilicate Catalysts by X-ray Absorption Fine Structure Spectroscopy
Juan J. Bravo-Suárez,Kyoko K. Bando,Ji-Qing Lu,Masatake Haruta,Tadahiro Fujitani,S. Ted Oyama +5 more
TL;DR: In this paper, in situ ultraviolet-visible (UV−vis) diffuse reflectance spectroscopy was used in combination with in situ Ti K-edge X-ray absorption near-edge structure (XANES) to study the formation of Ti-hydroperoxo species during the gas-phase epoxidation of propylene with H2 and O2 at reaction conditions over a Au−Ba/Ti−SiO2 (Ti−TUD) catalyst.
Journal ArticleDOI
Catalytic transfer hydrogenation of biomass-derived levulinic acid and its esters to γ-valerolactone over ZrO2 catalyst supported on SBA-15 silica
Yasutaka Kuwahara,Yasutaka Kuwahara,Wako Kaburagi,Yohsuke Osada,Tadahiro Fujitani,Hiromi Yamashita,Hiromi Yamashita +6 more
TL;DR: A series of ZrO2 catalysts supported on mesoporous SBA-15 silica were synthesized and examined as catalysts in the production of γ-valerolactone (GVL) from biomass-derived levulinic acid and its esters via a catalytic transfer hydrogenation (CTH) using several alcohols as hydrogen donors as mentioned in this paper.
Journal ArticleDOI
Synthesis of high-silica CHA type zeolite by interzeolite conversion of FAU type zeolite in the presence of seed crystals
Masaya Itakura,Ikuhiro Goto,Atsushi Takahashi,Tadahiro Fujitani,Yusuke Ide,Masahiro Sadakane,Tsuneji Sano +6 more
TL;DR: In this paper, the influence of seed crystals on the interzeolite conversion of FAU type zeolite into CHA types was investigated in the presence of benzyltrimethylammonium hydroxide as a structure-directing agent under various hydrothermal synthesis conditions.
Journal ArticleDOI
Evidence for the migration of ZnOx in a Cu/ZnO methanol synthesis catalyst
TL;DR: In this paper, the behavior and role of ZnO in Cu/ZnO catalysts for the hydrogenations of CO and CO2 were studied using XRD, TEM coupled with EDX, TPD and FT-IR.
Journal ArticleDOI
Esterification of levulinic acid with ethanol over sulfated Si-doped ZrO2 solid acid catalyst: Study of the structure–activity relationships
TL;DR: In this paper, the structural properties and catalytic performance of ZrO 2 solid acid catalysts with enlarged surface areas and the relationships between these properties and the catalytic performances were investigated, which suggested that the number of accessible active acid sites and the accessibility of the organic reactants to the active sites play crucial roles in determining the overall activity.
