CO2 reforming of methane over Ni-Ru supported catalysts: On the nature of active sites by operando DRIFTS study
(Elsevier, 2018)
The present paper addresses the nature of the active sites of a bimetallic Ni-Ru supported catalyst on the dry reforming of methane (DRM). The structural characterization by XRD and Raman spectroscopy, along with ...

H2 oxidation as criterion for PrOx catalyst selection: Examples based on Au-CoOx-supported systems
(Elsevier, 2015-06-01)
A new approach for understanding PrOx reaction over gold catalysts is proposed in this work. The competition between H2 and CO oxidation has been studied over a series of Au/MOx/Al2O3 (M = Ce and Co) catalysts in simulated ...

Low-temperature CO oxidation on multicomponent gold based catalysts
(Frontiers Media S.A, 2013)
In this work the development of gold catalysts, essentially based on γ-alumina with small superficial fraction of Ce-Fe mixed oxides as support for the low temperature CO oxidation is proposed. Characterization results ...

Fe-doped ceria solids synthesized by the microemulsion method for CO oxidation reactions
(Elsevier, 2011)
A series of Ce-Fe mixed oxides as well as the pure oxides were synthesized by the microemulsions method. The solid solution formation was established for all the Fe-doped systems and only a hardly noticeable segregation ...

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 ...
