Design of catalyst systems for the one-pot synthesis of menthols from citral
(Academic Press Inc Elsevier Science, 2007-04)
Stable, active, and highly selective bifunctional Ni/Al-MCM-41 catalysts were developed for the one-pot synthesis of menthols from citral. The liquid-phase hydrogenation of citral to citronellal was studied on silica-supported ...
Composite H3PW12O40–TiO2 catalysts for toluene selective photo-oxidation
(Elsevier Science, 2018-06-05)
A series of composite systems based on titania and growing quantities of tungstophosphoric acid are prepared and characterized using infrared, nuclear resonance, UV–visible, photoluminescence, and photoelectron spectroscopies, ...
Composite H3PW12O40–TiO2 catalysts for toluene selective photo-oxidation
(Elsevier Science, 2017-11-22)
A series of composite systems based on titania and growing quantities of tungstophosphoric acid are prepared and characterized using infrared, nuclear resonance, UV–visible, photoluminescence, and photoelectron spectroscopies, ...
Catalytic and spectroscopic study of the allylic alcohol synthesis by gas-phase hydrogen transfer reduction of unsaturated ketones on acid-base catalysts
(Elsevier Science, 2006-08)
The hydrogen transfer reduction of an α,β-unsaturated ketone, mesityl oxide, was studied on several single oxides in the gas-phase using 2-propanol as a hydrogen source. Selectivity is essentially determined by oxide ...
Catalytic oxidation of sulfur compounds over Ce-SBA-15 and Ce-Zr-SBA-15
(Elsevier Science, 2021-01)
The catalytic oxidation of different sulfur compounds, commonly present in liquid fuel, was studied over a series of ceria and ceria-zirconium based oxidation mesoporous catalysts. SBA-15 was synthesized using sol-gel ...
Selective lactose oxidation in aqueous-phase over Ag-Au bimetallic nanoparticles supported on Al 2 O 3 under mild reaction conditions
(Elsevier B.V., 2018-12-01)
In this work, Au-Ag based catalysts supported on Al 2 O 3 were prepared by a precipitation-deposition method at controlled pH and tested in the selective lactose (LA) oxidation to lactobionic acid (LB) in aqueous phase. ...
Understanding the Role of Protic Ionic Liquids (PILs) in Reactive Systems: Rational Selection of PILs for the Design of Green Synthesis Strategies for Allylic Amines and β‐Amino Esters
(Wiley-VCH Verlag, 2019-07)
The reactive behaviour of protic ionic liquids (PILs) has been shown to be governed not only by their chemical structures but also by their global compositions, which include the presence of free acids and bases at equilibrium ...
Solketal synthesis from ketalization of glycerol with acetone: A kinetic study over a sulfated zirconia catalyst
(Elsevier Science, 2021-07-15)
In this work, a series of acid catalysts were synthetized from a commercial zirconium oxide sulfated with a 0.5 M H2SO4 solution by wet impregnation. The characterization results show a correlation between the calcination ...
Ni-supported catalysts on mesoporous carbon modified by Al(H2PO4)3 to obtain 1-propanol
(Elsevier Science, 2021-07-26)
The aim of this work was to investigate the catalytic properties of nickel over a carbon-based support modified with phosphorus for the hydrogenolysis of glycerol to obtain 1-propanol. For this, a series of nickel phosphide ...
The origin of the enhanced activity of Pt/zeolites for combustion of C2-C4 alkanes
(Elsevier Science, 2007-04)
The deep oxidations of ethane, propane and butane were studied on Pt supported on MgO, alumina, and zeolites KL, HY, ZSM5, and Beta. The catalyst activities were evaluated through both conversion versus temperature (light-off ...
