Nitrate Removal on a Cu/Cu2O Photocathode under UV Irradiation and Bias Potential
(2013-01-01)
The present work describes a suitable method for treatment of water contaminated with nitrate by using a photoelectrochemical method. A Cu/Cu 2O electrodeposited electrode is used as photocathode with long-term stability ...
Electrochemical preparation of Cu/Cu2O-Cu(BDC) metal-organic framework electrodes for photoelectrocatalytic reduction of CO2
(2020-12-01)
Thin films of the metal-organic framework (MOF) Cu(BDC) were electrochemically grown by anodic deposition of the ligand 1,4-benzenedicarboxylate (1,4-BDC) on metallic copper to form Cu/Cu2O-Cu(BDC) electrode. The construction ...
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 ...
Caracterização óptica de nanopartículas de CuCl e CuBr sintetizadas em filmes ORMOSILs
(Universidade Estadual Paulista (Unesp), 2017-03-15)
A incorporação de nanopartı́culas em matrizes hı́bridas produz materiais com grande potencial para aplicações em diversas áreas de estudo. Na óptica, sua funcionalidade surge quando elétrons confinados em estruturas ...
Highly active Rb/Cu/YCeO2 catalyst for the storage of nitric oxide under lean conditions
(ELSEVIER SCIENCE BV, 2016)
A novel Pt-free Rb/Cu/YCeO2 catalyst was applied to the adsorption of NO under oxidizing conditions. The results show a much greater performance of this catalyst relative to a Pt/Ba/Al2O3 catalyst. The results suggest that ...
Efeito do tamanho de partículas de Cu nas propriedades estruturais e eletrônicas e suas correlações com propriedades catalíticas na desidrogenação do etanol em Cu/SiO2
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2019-03-08)
Metal nanoparticles may exhibit distinct catalytic behavior when there are particle size variations at nanometric scale. Cu nanoparticles supported on SiO2 and CAB-O-SIL® were synthesized with different metal loadings by ...
