Selective CO methanation with structured RuO2/Al2O3 catalysts
(Elsevier, 2018)
Active and selective structured RuO2/Al2O3 catalysts for CO methanation using a flow simulating CO2-rich reformate gases from WGS and PROX units (H2 excess, CO2 presence and 300 ppm CO concentration) were prepared. Both, ...

A direct in situ observation of water-enhanced proton conductivity of Eu-doped ZrO2: Effect on WGS reaction
(Elsevier, 2018)
Eu-doped ZrO2 solid solutions have been synthesized in order to prepare proton conductors as water-enhancer additives for the WGS reaction. Elemental characterization has been carried out revealing homogeneous ...

Pt/CePO4 catalysts for the WGS reaction: influence of the water-supplier role of the support on the catalytic performance
(Royal Society of Chemistry, 2018)
For Pt catalysts which have demonstrated great activity for the WGS reaction, the activation of water is described as the rate-limiting step. Such limitation could be overcome through the design of supports able to supply ...

Does shaping catalysts modify active phase sites? A comprehensive in situ FTIR spectroscopic study on the performance of a model Ru/Al2O3 catalyst for the CO methanation
(Elsevier, 2018)
Routinely, it seems assumed that the catalytic layer coated on monoliths and microchannel reactors preserve the properties of the initial powder catalyst. However, this assumption should be reasonably demonstrated since ...

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 ...

Multicomponent Ni-CeO2 nanocatalysts for syngas production from CO2/CH4 mixtures
(Elsevier, 2018)
The dry reforming of methane with CO2 is a common route to transform CO2/CH4 mixtures into added value syngas. Ni based catalysts are highly active for this goal but suffer from deactivation, as such promoters need to be ...

Phosphate-type supports for the design of WGS catalysts
(Elsevier, 2018)
The importance of water availability during the WGS reaction has been extensively reported. Thus, the search of new supports able to interact with the water molecule is of great importance. In this work, a series of ...

Operando DRIFTS-MS Study of WGS and rWGS Reaction on Biochar-Based Pt Catalysts: The Promotional Effect of Na
(MDPI, 2018)
Biochar-based Pt catalysts, unpromoted and Na-promoted, were prepared by an incipient wetness impregnation method and characterised by Inductively coupled plasma mass spoectrometry (ICP-MS) analysis, X-ray diffraction, N2 ...

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 ...
