Liquid phase hydrogenation of cinnamaldehyde on Cu-based catalysts
(Elsevier Science, 2003-08)
The liquid phase hydrogenation of cinnamaldehyde was studied at 393 K and 10 bar on Cu-based catalysts containing about 12 wt.% of copper. Cu/SiO 2 was prepared by incipient wetness impregnation while Cu-Al, Cu-Zn-Al, and ...
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 ...
