Influence of gold particle size in Au/C catalysts for base-free oxidation of glucose
(Elsevier, 2017)
A series of gold colloids were prepared and immobilized on commercial activated carbon. The influence of the colloid preparation and stability were studied and related to the gold particle size in the final catalyst. The ...

WGS and CO-PrOx reactions using gold promoted copper-ceria catalysts: “bulk CuO-CeO2 vs. CuO-CeO2/Al2O3 with low mixed oxide content”
(Elsevier, 2016)
A copper-ceria bulk catalyst has been compared to a series of catalysts designed according to the as called “supported approach”, corresponding to the dispersion of low content mixed copper-ceria oxide on alumina matrix. ...

Fischer–Tropsch Synthesis Over Zr-Promoted Co/γ-Al2O3 Catalysts
(Springer, 2017)
Two Zr-modified alumina supports were synthetized containing the same amount of Zr but a different distribution of this modifier over the alumina surface. These supports, together with the unmodified alumina carrier, were ...

Intensifying glycerol steam reforming on a monolith catalyst: a reaction kinetic model
(Elsevier, 2016)
In this work, a structured monolithic catalyst has been tested under a wide range of conditions (partial pressure, residence time, temperature and time-on-stream), with the aim of modeling its kinetic behavior and assessing ...

Influence of the ionic liquid presence on the selective oxidation of glucose over molybdenum based catalysts
(Elsevier, 2016-12-01)
Two different approaches are proposed in this work in order to study the influence of the ionic liquid presence in the reaction of glucose oxidation by H2O2 in mild conditions. The ionic liquids are applied either as a ...

Ru–Ni Catalyst in the Combined Dry-Steam Reforming of Methane: The Importance in the Metal Order Addition
(Springer Verlag, 2016)
Biogas is one of the main biomass-energy resources. Its use for syngas production with a H2/CO ratio close to two would have huge environmental, social and economic impact in the actual energetic scenario. However, the use ...

O2-assisted Water Gas Shift reaction over structured Au and Pt catalysts
(Elsevier, 2016)
Platinum and gold structured catalysts were compared as active phases in classical and O2-assisted Water Gas Shift (WGS) reaction. Both metals were supported on iron-doped ceria mixed oxide and then, structured on metallic ...

The role of Au, Cu & CeO2 and their interactions for an enhanced WGS performance
(Elsevier, 2016)
The WGS reaction over multicomponent Au/Ce1-xCuxO2/Al2O3 catalysts is studied in this work. The systems are carefully designed aiming to take advantage of every active phase included in the formulation: gold, ceria and ...

Monitoring the Reaction Mechanism in Model Biogas Reforming by In Situ Transient and Steady-State DRIFTS Measurements
(Wiley-VCH, 2017)
In this work, the reforming of model biogas was investigated on a Rh/MgAlO catalyst. In situ transient and steady-state diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) measurements were used to gain ...

Boosting the activity of a Au/CeO2/Al2O3 catalyst for the WGS reaction
(Elsevier, 2015)
Herein a strategy to design highly efficient Au/CeO2/Al2O3 based WGS catalysts is proposed. The inclusion of transition metals, namely Fe, Cu and Zn as CeO2 dopant is considered. All the promoters successfully increased ...
