Pt vs. Au in water-gas shift reaction
(Elsevier, 2014)
This work presents a comparison of the gold- and platinum-based catalysts behavior in the water-gas shift (WGS) reaction. The influence of the support, e.g., its composition and electronic properties, studied in detail by ...

Recent advances on gas-phase CO2 conversion: Catalysis design and chemical processes to close the carbon cycle
(Elsevier, 2022)
Chemical CO2 recycling in the gas phase constitutes a straightforward approach for effective CO2 conversion to added-value products like syngas or synthetic methane. In this scenario, some traditional processes such as the ...

Au/CeO2 metallic monolith catalysts: Influence of the metallic substrate
(World Gold Council, 2013)
Ceria-based gold catalysts were successfully deposited on ferritic stainless steel (Fecralloy) and aluminium monoliths. The prepared monolithic and reference powder catalysts were characterized by means of S BET, X-ray ...

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 ...

Nanogold mesoporous iron promoted ceria catalysts for total and preferential CO oxidation reactions
(Elsevier, 2016)
Herein, a series of highly efficient gold based catalysts supported on mesoporous CeO2-Fe2O3 mixed oxides for CO elimination reactions have been developed. The materials have been fully characterized by means of XRD, Raman ...

Functionalized Biochars as Supports for Ru/C Catalysts: Tunable and Efficient Materials for γ-Valerolactone Production
(MDPI, 2023)
Cotton stalks-based biochars were prepared and used to synthetize Ru-supported catalysts for selective production of γ-valerolactone from levulinic acid in aqueous media. Different biochars’ pre-treatments (HNO3, ZnCl2, ...
