Copper-gallia interaction in Cu-Ga2O3-ZrO2 catalysts for methanol production from carbon oxide(s) hydrogenation
(Elsevier Science, 2015-09)
The impact of the interaction between copper and gallia was studied over a selected set of supported(2 wt%) Cu on Ga2O3, ZrO2and Ga2O3–ZrO2catalysts, which were employed in the methanol synthesisfrom CO2and CO mixtures. ...
Catalizadores de Cu-Ga2o3/ZrO2 para la hidrogenación selectiva de óxidos de carbono hacia metanol
(2016-03-15)
It was studied the effect of Ga2O3 (gallia) as promoter, of ZrO2 (zirconia) as support and of the Cu-Ga2O3 and Cu-ZrO2 interactions, in the catalytic performance of supported copper catalysts in the reaction of methanol ...
A DFT Approach for Methanol Synthesis via Hydrogenation of CO on Gallia, Ceria and ZnO surfaces
(Elsevier Science, 2018-04-01)
A systematic theoretical study of the consecutive hydrogenation reactions of the CO molecule for the methanol synthesis catalyzed by different oxides of Zn, Ce and Ga is reported in this work. First, the CO hydrogenation ...
Efeito da Gália como aditivo de sinterização em eletrólitos cerâmicos à base de céria sintetizados pelo método de complexação de cátions

Fuel cells are considered one of the most promising ways of converting electrical
energy due to its high yield and by using hydrogen (as fuel) which is considered one of
the most important source of clean energy for ...
Isotopic study of the rates of hydrogen provision vs. methanol synthesis from CO2 over Cu-Ga-Zr catalysts
(Academic Press Inc Elsevier Science, 2015-08)
Cu/ZrO2 and Ga2O3-promoted Cu/ZrO2, with the same copper loading (2.6 wt.%), were evaluated in a Carberry-type batch-operated microreactor for methanol synthesis using a H2/CO2/He mixture (75/22/3 v/v) at 1.6 MPa and 498 ...
Insights on hydride formation over cerium-gallium mixed oxides: a mechanistic study for efficient H2 dissociation
(Elsevier, 2017-01)
A four-step reaction mechanism is proposed for the H2 dissociation over pure ceria and Gallium promoted mixed oxide materials, in a combined experimental and computational investigation. Two samples of cerium-gallium mixed ...

Methanol synthesis from CO2/H2 using Ga2O3-Pd/SiO2 catalysts: Impact of reaction products
(Elsevier Science, 2008-12)
The synthesis of CH3OH from CO2/H2 mixtures using Ga2O3–Pd/SiO2 promoted catalysts is strongly affected by the reaction products. At finite conversion, important amounts of water and carbon monoxide are also found in the ...
