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 ...

Deep insight into Zr/Fe combination for successful Pt/CeO2/Al2O3 WGS catalyst doping
(Royal Society of Chemistry (Great Britain), 2017)
Efficient promotion of the Pt/CeO/AlO catalytic system was achieved by the addition of two different ceria promoters, Zr and Fe. From the exhaustive data analysis, the key features for enhanced catalytic performance and ...

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 ...

Structuring Pt/CeO2/Al2O3 WGS catalyst: Introduction of buffer layer
(Elsevier, 2017)
This work is devoted to the development of novel structured catalytic system for WGS reaction. The new concept is related to the presence of a pre-catalytic “buffer” layer formed by WGS-inert oxide, i.e. not involved in ...

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 ...

Gold catalysts screening in base-free aerobic oxidation of glucose to gluconic acid
(Elsevier, 2017-01-01)
Base-free aerobic oxidation of glucose in presence of Au/Al2O3, Au/CeO2, Au/CeO2(20 wt%)/Al2O3, Au/CeO2(25 wt%)/ZrO2 and Au/CeO2(50 wt%)/ZrO2 catalysts using molecular oxygen at atmospheric pressure is studied. Within the ...
