Co-Fe Clusters Supported on N-Doped Graphitic Carbon as Highly Selective Catalysts for Reverse Water Gas Shift Reaction

Peng, Lu; Jurca, Bogdan; Primo Arnau, Ana Maria; Gordillo, Alvaro; Parvulescu, Vasile I.; García Gómez, Hermenegildo (American Chemical Society, 2021-07-19)

[EN] Graphitic carbons are suitable supports of metal nanoparticles with catalytic activity. In the present study, the preparation of N-doped graphitic carbon supporting clusters of Fe-Co alloys starting from biomass waste ...
CO2 methanation catalyzed by oriented MoS2 nanoplatelets supported on few layers graphene

Primo Arnau, Ana Maria; He, Jinbao; Jurca, Bogdan; Cojocaru, Bogdan; Bucur, Cristina; Parvulescu, Vasile I.; García Gómez, Hermenegildo (Elsevier, 2019-05-15)

[EN] Powders of molybdenum disulfide platelets strongly grafted on graphene have been prepared by pyrolysis of ammonium alginate containing adsorbed various proportions of (NH4)(2)MoS4. After pyrolysis, formation of MoS2 ...
Doped graphenes in catalysis

Albero, Josep; García Gómez, Hermenegildo (Elsevier, 2015-11)

[EN] Due to the availability and easy preparation, graphenes are currently under intense investigation for various applications in chemistry including their use as metal-free catalysts. The presence in low percentage of ...
Graphene Film-Supported Oriented 1.1.1 Gold(0) Versus 2.0.0 Copper(I) Nanoplatelets as Very Efficient Catalysts for Coupling Reactions

Candu, Natalia; Simion, Andrada; Coman, Simona M.; Primo Arnau, Ana Maria; Esteve-Adell, Iván; Parvulescu, Vasile I.; García Gómez, Hermenegildo (Springer-Verlag, 2018)

[EN] Few-layered graphene-supported 1.1.1 and 2.0.0 oriented Au and Cu2O nanoplatelets were prepared by one-step pyrolysis of the corresponding metal salts embedded in chitosan at 900 degrees C under inert atmosphere. These ...
Metal nanoparticles supported on two-dimensional graphenes as heterogeneous catalysts

Navalón Oltra, Sergio; Dhakshinamoorthy, Amarajothi; Alvaro Rodríguez, Maria Mercedes; García Gómez, Hermenegildo (Elsevier, 2016)

[EN] The catalytic activity of metal nanoparticles (MNPs) is highly dependent on the nature of the support. In addition to the role of particle size stabilization in decreasing the spontaneous growth of small MNPs, the ...
Nanometer-thick films of antimony oxide nanoparticles grafted on defective graphenes as heterogeneous base catalysts for coupling reactions
