W@Au Nanostructures Modifying Carbon as Materials for Hydrogen Peroxide Electrogeneration
(2017-03-20)
In this work, materials based on core-shell W@Au type structures were found to have promise for use as electrocatalysts on the in-situ production of H2O2 by means of the oxygen reduction reaction (ORR). We describe herein ...
A theoretical approach of the ethanol adsorption on Au(100), Au(110) and Au(111) surfaces
(ElsevierNL, 2019)
The adsorption of ethanol on Au(100), Au(110) and Au(111) surfaces was studied using electronic structure calculations under the scheme of the density functional theory (DFT) with van der Waals corrections, vdW-DF2 and PBE ...
Synergetic Effect of Bimetallic Au-Ru/TiO2 Catalysts for Complete Oxidation of Methanol
(Elsevier Science, 2017-01)
Bimetallic Ru-Au/TiO2 catalysts prepared by deposition-precipitation with urea method were tested for the first time in the total oxidation of methanol. Different Ru:Au atomic ratios were used (1:1–0.25:1). The catalytic ...
Catalisadores de Au/ZrO2 e Au/In2O3/ZrO2: Efeito das propriedades eletrônicas e estruturais na atividade para desidrogenação do etanol e hidrogenação de CO2
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2022-10-28)
Au/ZrO2 and Au/In2O3/ZrO2 catalysts were developed for CO2 hydrogenation reaction and Au/ZrO2 for ethanol dehydrogenation. The monometallic gold catalysts supported on ZrO2 with different contents (0.3 to 5.0%w/w) were ...
Co oxidation: effect of Ce and Au addition on MnOx catalysts
(Planta Piloto de Ingeniería Química, 2012-10)
The effect of cerium and/or gold addition to a manganese oxide which was greatly active in CO oxidation was studied. The catalysts obtained by this way were characterized by N2 adsorption, XRF, XRD and TPR, and their ...

Interstitial oxygen related defects and nanovoids in Au implanted a-SiO2 glass depth profiled by positron annihilation spectroscopy
(IOP Publishing, 2015-11)
Samples of amorphous silica were implanted with Au ions at an energy of 190 keV and fluences of 1×1014 ions cm−2and 5×1014 ions cm−2 at room temperature. The damage produced by ion implantation and its evolution with the ...
