Selective liquid-phase hydrogenation of furfural to furfuryl alcohol over Cu-based catalysts
(Elsevier, 2013-02)
In this work, the liquid-phase furfural hydrogenation over different Cu-based catalysts was studied. The catalysts were prepared by incipient wetness impregnation (Cu/SiO2-I), precipitation?deposition(Cu/SiO2-PD) and ...

Microscopia de tunelamento em moléculas de tetrafenilporfirina de Co em monocamadas isolantes de Cu2N sobre Cu(100)
(2019)
Este trabalho tem por objetivo o estudo das propriedades de moléculas detetrafenilporfirina de cobalto (CoTPP) depositadas em superfíciescristalinas através da técnica de microscopia/espectroscopia detunelamento por varredura ...
Structural and optical properties of Cu2O crystalline electrodeposited films
(Elsevier B.V., 2014-07-01)
Cuprous oxide (Cu2O) films were electrodeposited on Ni/Si(100), Au/Si(100), and Si(100) substrates from aqueous solution at room temperature. The thicknesses of the films were varied in the range of 250 to 1250 nm. It was ...
Electronic properties of transition metal atoms on Cu2N/Cu(100)
(American Physical Society, 2015-11)
We study the nature of spin excitations of individual transition metal atoms (Ti, V, Cr, Mn, Fe, Co, and Ni) deposited on a Cu2N/Cu(100) surface using both spin-polarized density functional theory (DFT) and exact diagonalization ...
Monte Carlo simulations and cluster-exact approximation applied to H/Cu(100),H/Ag(100) and O/Cu(100) systems
(Elsevier Science, 2020-01)
The systems H/Cu(100),H/Ag(100) and O/Cu(100) were analyzed theoretically by means of DFT calculations, Monte Carlo (MC) simulations and a Cluster-exact (CA) Approximation. To model these real systems, a two stages procedure ...
Photocatalytic degradation of methylene blue by TiO2-Cu thin films: Theoretical and experimental study
(Elsevier B.V., 2010-12-15)
In this work the effect of doping concentration and depth profile of Cu atoms on the photocatalytic and surface properties of TiO2 films were studied. TiO2 films of about 200 nn thickness were deposited on glass substrates ...
