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 ...

Time-resolved Operando DRIFTS-MS Study of the Moisture Tolerance of Small-pore SAPO-34 Molecular Sieves During CH4/CO2 Separation
(Elsevier, 2020)
This study pretends to evaluate and understand the effect of moisture presence during CO2/CH4 separation on small-pore SAPO-34 molecular sieves. Two SAPO-34 samples with different physicochemical properties (composition, ...

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 ...

Free-Carbon Surface for PtCu Nanoparticles: An in Situ near Ambient Pressure X-ray Photoelectron Spectroscopy Study
(American Chemical Society, 2020)
Usually, nanoparticle synthesis methodologies require the use of organic molecules (capping agent, solvent molecules, etc.), which results in carbon deposits on the nanoparticle surface. These residues modify the surface ...

Oxidation of CO over gold supported on Zn-modified ceria catalysts
(Elsevier, 2011)
A series of Zn-modified ceria solids were prepared by thermal decomposition of the corresponding metal propionates. The formation of segregated ZnO particles on the ceria surface is evidenced for these solids using X-ray ...
Article
Surface oxygen vacancies in gold based catalysts for CO oxidation
(RSC Publishing, 2014)
Experimental catalytic activity measurements, Diffuse Reflectance Infrared Fourier Spectroscopy, and Density Functional Theory calculations are used to investigate the role and dynamics of surface oxygen vacancies in the ...
Article
In situ DRIFTS-MS methanol adsorption study onto supported NiSn nanoparticles: Mechanistic implications in methanol steam reforming
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Methanol adsorption over both supported NiSn Nps and analogous NiSn catalyst prepared by impregnation was studied by in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) to gain insights into the ...

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 ...
