Active biopolymers in green non-conventional media: a sustainable tool for developing clean chemical processes
Royal Society of Chemistry (2015-10-15)The greenness of chemical processes turns around two main axes: the selectivity of catalytic transformations, and the separation of pure products. The transfer of the exquisite catalytic efficiency shown by enzymes in ... -
Catalyst design for highly efficient carbon dioxide hydrogenation to formic acid under buffering conditions
Elsevier (2020-03-19)We report on new ruthenium complexes as catalysts for the efficient transformation of CO2 into formic acid employing basic ionic liquids as buffering media. Remarkably, these complexes catalyze the hydrogenation of CO2 ... -
Chemoselective Hydrogenation of Nitroarenes Catalyzed by Molybdenum Sulphide Clusters
Wiley (2017-03-20)Herein, we describe an atom efficient and general protocol for the chemoselective hydrogenation of nitroarenes to anilines catalyzed by well-defined diimino and diamino cubane-type Mo3S4 clusters. The novel diimino ... -
Dual role of graphene as support of ligand-stabilized palladium nanoparticles and carbocatalyst for (de)hydrogenation of N-heterocycles
Elsevier (2023-02-18)The hybrid material composed of palladium nanoparticles (PdNPs) functionalized with N-heterocyclic carbene ligands (NHCs) immobilized onto the surface of reduced graphene oxide (rGO) results in an efficient catalytic ... -
Multimetallic (de)hydrogenation catalysed processes
WILEY-VCH (2016)The use of different metals working together in a synergistic way, allows synthetic transformations that are not achievable by other means. The metal cooperation becomes important in catalytic processes for the synthesis ... -
Nanolayered cobalt–molybdenum sulphides (Co–Mo–S) catalyse borrowing hydrogen C–S bond formation reactions of thiols or H2S with alcohols
Royal Society of Chemistry (2019)Nanolayered cobalt–molybdenum sulphide (Co–Mo–S) materials have been established as excellent catalysts for C–S bond construction. These catalysts allow for the preparation of a broad range of thioethers in good to excellent ... -
Palladium doping of In2O3 towards a general and selective catalytic hydrogenation of amides to amines and alcohols
Royal Society of Chemistry (2019-11)Herein, the first general heterogeneous catalytic protocol for the hydrogenation of primary, secondary and tertiary amides to their corresponding amines and alcohols is described. Advantageously, this catalytic protocol ... -
Recent Developments in the Modelling of Heterogeneous Catalysts for CO2 Conversion to Chemicals
Wiley-VCH Verlag (2020-04-06)Density functional theory (DFT) of the CO2 behavior on the catalyst surface provides valuable insights about the C=O bond activation, information about adsorption and dissociation of CO2, understanding the elementary steps ... -
Role of Pd in the Electrochemical Hydrogenation of Nitrobenzene Using CuPd Electrodes
Wiley (2022-04)Interest in the electrochemical reduction of organic compounds as an alternative to hydrogen electrosynthesis is driven, among other reasons, by the fact that the products obtained in this process may have more economic ... -
Stabilization of Nanoparticles Produced by Hydrogenation of Palladium–N-Heterocyclic Carbene Complexes on the Surface of Graphene and Implications in Catalysis
American Chemical Society (2018)Palladium nanoparticles (NPs) have been obtained by decomposition of well-defined palladium complexes noncovalently anchored onto the surface of reduced graphene oxide. Morphological analysis by microscopy showed the ... -
Visible-Light-Promoted Iridium(III)-Catalyzed Acceptorless Dehydrogenation of N-Heterocycles at Room Temperature
American Chemical Society (2022-05-10)An effective visible-light-promoted iridium(III)-catalyzed hydrogen production from N-heterocycles is described. A single iridium complex constitutes the photocatalytic system playing a dual task, harvesting visible-light ...
