Photocatalytic degradation of methylene blue by TiO(2)-Cu thin films: Theoretical and experimental study
(ELSEVIER SCIENCE BV, 2010)
In this work the effect of doping concentration and depth profile of Cu atoms on the photocatalytic and surface properties of TiO(2) films were studied. TiO(2) films of about 200 nn thickness were deposited on glass ...
Metal-phthalocyanine ordered layers on Au(110): Metal-dependent adsorption energy
(American Institute Of Physics, 2014-06)
Iron-phthalocyanine and cobalt-phthalocyanine chains, assembled along the Au(110)-(1×2) reconstructed channels, present a strong interaction with the Au metallic states, via the central metal ion. X-ray photoemission ...
Photodegradation of methylene blue by in situ generated titania supported on a NaA zeolite
(2009)
The degradation of methylene blue dye was evaluated for a series of in situ generated titania resulting from the impregnation of TiCl4 into a series of NaA zeolites, which were synthesized using alternative silicon sources, ...
On the interaction of encapsulated pH indicator species within a silica matrix produced by three sol–gel routes
(2011)
Solid acid–base sensors were prepared by encapsulating two pH indicators (brilliant yellow or acridine) within a silica matrix by the sol–gel method using three different routes: (1) non-hydrolytic, (2) acid catalyzed and ...
Anchoring lead-free halide Cs3Bi2I9 perovskite on UV100–TiO2 for enhanced photocatalytic performance
(Elsevier Science, 2020-01)
Halide perovskites have shown great potential in photocatalytic applications. In order to enhance the charge transportation efficiency, the chemical stability, and the light absorption ability, we anchored a lead-free ...
Photoionization of water molecules by a train of attosecond pulses assisted by a near-infrared laser: Delay and polarization control
(the International Society for Optical Engineering, 2017-09)
Basic reactions involving water molecules are essential to understand the interaction between radiation and the biological tissue because living cells are composed mostly by water. Therefore, the knowledge of ionization ...
Influence of silver electrochemically deposited onto zinc oxide seed nanoparticles on the photoelectrochemical performance of zinc oxide nanorod films
(SAGE Publications, 2019-05)
The present article examines the synthesis and characterization of zinc oxide nanorods grown on zinc oxide and silver nanoparticle seeds. Zinc oxide seeds were electrodeposited on a support of fluorine-doped tin oxide glass ...
Síntese ambientalmente sustentável e aplicação fotovoltaica de pontos quânticos Cu-In-S e Zn-Cu-In-S
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2021-04-27)
The use of fossil fuels as an energy source has resulted in great social, environmental
and economic costs, making the search for alternative energy sources one of the main
priorities of modern society. Solar energy ...
