Composites of laminar nanostructured ZnO and VOx - Nanotubes Hybrid as visible light active photocatalysts

Benavente Espinosa, Eglantina; Navas, Daniel; Devis, Sindy; Segovia, Marjorie; Sotomayor Torres, Clivia; González Moraga, Guillermo (MDPI, 2018)

A series of hybrid heterostructured nanocomposites of ZnO with V2O5 nanotubes (VOx-NTs) in different mixing ratios were synthesized, with the aim of reducing the recombination of photoinduced charge carriers and to optimize ...

Incorporation of nanostructured ReO3 in silica matrix and their activity toward photodegradation of blue methylene

Díaz Valenzuela, Carlos; Valenzuela, M. L.; Cifuentes Vaca, O.; Segovia, Marjorie; Laguna Bercero, M. A. (Springer, 2020)

ReO3 were prepared by thermal treatment of the macromolecular Chitosan center dot(ReCl3)(X) and PSP-4-PVP center dot(ReCl3)(X) precursors. The plasmon band in the visible region for the as obtained ReO3 from their visible ...

Incorporation of NiO into SiO2, TiO2, Al2O3, and Na4.2Ca2.8(Si6O18) matrices: medium effect on the optical ...

Alvarado Díaz, Carlos; Valenzuela, María L.; Cifuentes Vaca, Olga; Segovia, Marjorie; Laguna Bercero, Miguel A. (MDPI, 2020)

The medium effect of the optical and catalytic degradation of methylene blue was studied in the NiO/SiO2, NiO/TiO2, NiO/Al2O3, and NiO/Na4.2Ca2.8(Si6O18) composites, which were prepared by a solid-state method. The new ...
