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 ...
Graphene supported NiO/Ni nanoparticles as efficient photocatalyst for gas phase CO2 reduction with hydrogen

Mateo-Mateo, Diego; Albero-Sancho, Josep; García Gómez, Hermenegildo (Elsevier, 2018-05)

[EN] The photocatalytic activity of NiO/Ni nanoparticles (NPs) supported on defective graphene (NiO/Ni-G) has been tested for the photoassisted CO2 reduction with H-2. NiO/Ni-G was prepared by H-2 reduction of NiCl2 adsorbed ...
