Flexible syngas production using a La2Zr2-xNixO7-δ pyrochlore-double perovskite catalyst: Towards a direct route for gas phase CO2 recycling
(Elsevier, 2020)
The bi-reforming of methane (BRM) has the advantage of utilising greenhouse gases and producing H2 rich syngas. In this work Ni stabilised in a pyrochlore-double perovskite structure is reported as a viable catalyst for ...

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 ...

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 ...

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 ...

Au/CeO2 catalysts: structure and CO oxidation activity
(Multidisciplinary Digital Publishing Institute (MDPI), 2016)
In this comprehensive review, the main aspects of using Au/CeO2 catalysts in oxidation reactions are considered. The influence of the preparation methods and synthetic parameters, as well as the characteristics of the ceria ...

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 ...

Multicomponent Au/Cu-ZnO-Al2O3 catalysts: Robust materials for clean hydrogen production
(Elsevier, 2018)
Clean hydrogen production via WGS is a key step in the development of hydrogen fuel processors. Herein, we have designed a new family of highly effective catalysts for low-temperature WGS reaction based on gold modified ...
