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. ...

Fructose dehydration reaction over functionalized nanographitic catalysts in MIBK/H2O biphasic system
(Elsevier, 2021)
A series of functionalized nanographitic carbons is prepared, characterized and tested in fructose dehydration reaction to 5-hydroxymethylfurfural. The functionalization treatment was selected to introduce various Brönsted ...

Ni-CeO2/C Catalysts with Enhanced OSC for the WGS Reaction
(MDPI AG, 2015)
In this work, the WGS performance of a conventional Ni/CeO2 bulk catalyst is compared to that of a carbon-supported Ni-CeO2 catalyst. The carbon-supported sample resulted to be much more active than the bulk one. The higher ...

Gold catalyst recycling study in base-free glucose oxidation reaction
(Elsevier, 2018)
This work is devoted to the study of viability of immobilized gold colloids on carbon as catalysts for the base-free glucose oxidation reaction with a special emphasis made on catalysts’ recycling, operational life and ...

Mono and bimetallic Cu-Ni structured catalysts for the water gas shift reaction
(Elsevier, 2015)
The water-gas shift (WGS) reaction over structured Cu, Ni, and bimetallic Cu-Ni supported on active carbon (AC) catalysts was investigated. The structured catalysts were prepared in pellets form and applied in the medium ...

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 ...

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 ...

Tailoring structured WGS catalysts: Impact of multilayered concept on the water surface interactions
(Elsevier, 2018)
A novel multilayer approach for designing structured WGS catalyst is employed in this study as a response to the lack of new strategies in the literature. The approach proposes the use of two successive layers with ...
