Highly selective 1-butanol obtained from ethanol catalyzed by mixed metal oxides: Reaction optimization and catalyst structure behavior
(2019-10-01)
Synthesis and characterization of a copper mixed metal oxide obtained from hydrotalcite precursor as well as catalytic runs for ethanol conversion to 1-butanol are described. Applying the surface response model, the reaction ...
Mixed metal oxides from sucrose and cornstarch templated hydrotalcite-like LDHs as catalysts for ethyl biodiesel synthesis
(2017-01-01)
Sucrose and cornstarch were used as organic templates in the synthesis of hydrotalcite-like layered double hydroxides (LDHs) prepared by the coprecipitation with partial replacement of Mg by Zn, and Al by Fe. Non-template ...
Mixed oxides tuned with alkaline metals to improve glycerolysis for sustainable biodiesel production
(Elsevier Science, 2017-01)
In this study, monoglycerides were produced as glycerol value-added products via transesterification reaction of methyl stearate. This green and selective process involved catalysis from hydrotalcite-like compounds with ...
Comparison of UV and visible Raman spectroscopy of bulk metal molybdate and metal vanadate catalysts
(American Chemical Society, 2005-12)
The visible (532 and 442 nm) and UV (325 nm) Raman spectra of bulk mixed metal oxides (metal molybdates and metal vanadates) were compared on the same spectrometer, for the first time, to allow examination of how varying ...
Ni-Nb mixed oxides: One-pot synthesis and catalytic activity for oxidative dehydrogenation of ethane
(Elsevier Science, 2014-06-20)
Ni–Nb mixed oxides were prepared by two methods, conventional evaporation method and combustion synthesis. With the latter technique, the mixed oxide can be quickly prepared from an aqueous solution of metal precursors ...
Is there a relationship between the M=O bond length (strength) of bulk mixed metal oxides and their catalytic activity?
(Elsevier, 2008-03-10)
It is widely accepted in the catalysis literature that the bulk M=O bond of bulk mixed metal oxides controls catalytic activity. In the present study, for the first time, the bulk M=O bond lengths (strengths) and the surface ...
Mixed metal oxide Bi2O3/Bi2WO6 thin films for the photoelectrocatalytic degradation of histamine
(ElsevierNL, 2022)
Photoelectrocatalytic technologies emerge as competitive strategy to manage increasing histamine concentrations. This work explores the synergistic benefits induced in the formation of mixed oxide semiconductor in solid ...
First row transition metals on the ethanol Guerbet reaction: Products distribution and structural behavior of mixed metal oxides as catalysts
(2021-08-05)
Described is the transformation of ethanol into 1-butanol, acetaldehyde and other products by the Guerbet reaction (GR) over mixed metal oxides (MMOs) as catalysts. The MMOs, in which Mg2+ was partially (20 mol%) substituted ...
Co (II) porphyrin adsorbed on SiO2/SnO2/phosphate prepared by the sol-gel method
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
Application of manganese (II) phthalocyanine synthesized in situ in the SiO2/SnO2 mixed oxide matrix for determination of dissolved oxygen by electrochemical techniques
