Water-mediated photo-induced reduction of platinum films
(2019-06-11)
Article
Restricted access - publisher's policyPlatinum thin films activated ex situ by oxygen plasma become reduced by the combined effect of an intense soft X-ray photon beam and condensed water. The evolution of the electronic structure of the surface has been ... -
Thermodynamic assessment of non-catalytic Ceria for syngas production by methane reduction and CO2 + H2O oxidation
(2019-03-01)
Article
Open AccessChemical looping syngas production is a two-step redox cycle with oxygen carriers (metal oxides) circulating between two interconnected reactors. In this paper, the performance of pure CeO2/Ce2O3 redox pair was investigated ... -
Heterogeneous Fenton-like oxidation of p-hydroxybenzoic acid using Fe/CeO2-TiO2 catalyst
(2019-04-01)
Article
Restricted access - publisher's policyThis paper is built on the Fenton-like oxidation of p-hydroxybenzoic acid (p–HBZ) in the presence of H2O2 and 3%Fe supported on CeO2-TiO2 aerogels under mild conditions. These catalysts were deeply characterized by X-ray ... -
Techno-economic and exergy analysis of polygeneration plant for power and DME production with the integration of chemical looping CO 2 /H 2 O splitting
(Elsevier, 2019-04-15)
Article
Restricted access - publisher's policyIn this paper, we present a novel polygeneration plant with carbon capture for the combined power and dimethyl ether (DME) production. The plant layout integrates a chemical looping CO2/H2O splitting (CL) unit producing ... -

(2019-04-18)
Article
Restricted access - publisher's policyThis Review discusses novel catalytic pathways of lignocellulosic biomass to value-added chemicals including biomass-derived sugar alcohols, organic acids, furans and biohydrocarbons. These production approaches are ... -
Simulation of two-step redox recycling of non-stoichiometric ceria with thermochemical dissociation of CO 2 /H 2 O in moving bed reactors – Part II: Techno-economic analysis and integration with 100¿MW oxyfuel power plant with carbon capture
(2019-09-21)
Article
Restricted access - publisher's policyThis paper presents the model of a solar thermochemical looping CO2/H2O dissociation (CL) unit with commercial ceria as the redox oxygen carrier. The CL unit is integrated in an oxy-fuelled combined cycle power plant as ... -
Simulation of two-step redox recycling of non-stoichiometric ceria with thermochemical dissociation of CO 2 /H 2 O in moving bed reactors – Part I: Model development with redox kinetics and sensitivity analysis
(2019-03-29)
Article
Restricted access - publisher's policyChemical looping syngas production is a two-step process that produces CO and H2 from water and CO2 splitting. This is performed by exploiting a metal oxide as oxygen carrier material, which is thermally reduced and releases ... -
In situ environmental HRTEM discloses low temperature carbon soot oxidation by ceria-zirconia at the nanoscale
(2019-04-07)
Article
Restricted access - publisher's policyThe very close contact between ceria–zirconia and carbon soot allows the detection of oxygen transfer from ceria–zirconia to carbon by in situ Environmental HRTEM already at low temperatures. This highlights the outstanding ... -
