Catalytic Processes for Biomass-Derived Platform Molecules Valorisation

Ventura, Maria; Marinas, Alberto; Domine, Marcelo Eduardo (Springer-Verlag, 2020-09)

[EN] Nowadays, biomass is an interesting raw material for chemical industry, and the valorisation of its derivatives becomes in a sustainable alternative against to the depletion of fossil sources necessary for the production ...
Chemical and mechanical stability of BCZY-GDC membranes for hydrogen separation

Mercadelli, Elisa; Gondolini, Angela; Ardit, Matteo; Cruciani, Giuseppe; Melandri, Cesare; Escolástico Rozalén, Sonia; Serra Alfaro, José Manuel; Sanson, Alessandra (Elsevier, 2022-05-15)

[EN] This work investigates, for the first time, the hydrogen permeation of BaCe0.65Zr0.20Y0.15O3-delta-Ce0.8Gd0.2O2-delta (BCZY-GDC) asymmetric membranes for 100 h, using wet 15% CO2 in Ar as sweep gas. In the same frame, ...
Comparative Study of Epoxy-CsH2PO4 Composite Electrolytes and Porous Metal Based Electrocatalysts for Solid Acid Electrochemical Cells

Navarrete Algaba, Laura; Yoo, Chung-Yul; Serra Alfaro, José Manuel (MDPI AG, 2021-03)

[EN] Electrochemical cells based on acid salts (CsH2PO4) have attracted great interest for intermediate temperature, due to the outstanding proton conductivity of acid salts. In this work, electrodes and electrolyte were ...
Intensification of catalytic CO2 methanation mediated by in-situ water removal through a high-temperature polymeric thin-film composite membrane

Escorihuela-Roca, Sara; Cerdá-Moreno, Cristina; Remiro-Buenamañana, Sonia; Weigelt, Fynn; Escolástico Rozalén, Sonia; Tena, Alberto; Shishatskiy, Sergey; Brinkmann, Torsten; Chica, Antonio; Serra Alfaro, José Manuel (Elsevier, 2022-01)

[EN] Catalytic CO2 methanation technology can be improved by process intensification, i.e. enabling higher energy efficiency and process sustainability. Here, thin-film composite membranes (TFCM) were developed for in-situ ...
Isomerization of Glucose-to-Fructose in Water over a Continuous Flow Reactor using Ca-Al Mixed Oxide as Heterogeneous Catalyst

Ventura, Maria; Mazarío-Santa-Pau, Jaime; Domine, Marcelo Eduardo (John Wiley & Sons, 2022-02-08)

[EN] This work reports the continuous isomerization of glucose to fructose in aqueous media under mild conditions using a mixed oxide hydrotalcite-derived catalyst based on Ca and Al. Different operational parameters of ...
MOF-Mediated Synthesis of Supported Fe-Doped Pd Nanoparticles under Mild Conditions for Magnetically Recoverable Catalysis

Darawsheh, Mohanad D.; Mazarío-Santa-Pau, Jaime; Lopes, Christian W.; Gimenez-Marques, Monica; Domine, Marcelo Eduardo; Meira, Debora M.; Martínez, Jordan Santiago; Minguez Espallargas, Guillermo; Oña-Burgos, Pascual (John Wiley & Sons, 2020-10-27)

[EN] Metal-organic framework (MOF)-driven synthesis is considered as a promising alternative for the development of new catalytic materials with well-designed active sites. This synthetic approach is used here to gradually ...
Progress in Ce(0.8)Gd(0.2)O(2-delta)protective layers for improving the CO(2)stability of Ba0.5Sr0.5Co0.8Fe0.2O3-delta O2-transport membranes
