Possible Interaction: Copper and Zinc Oxide

“The doping of Cu with ZnO improved the selective cytotoxicity of ZnO NPs towards MCF7 and HeLa cells without affecting the normal cells.”

“Liver Cu content declined significantly as dietary ZnO concentration increased but there was a return towards normal after ZnO withdrawal.”

“ Cu– ZnO interactions promote CO2 hydrogenation to CH3OH by Zn-decorated Cu active sites.”

“The doped copper into the quantum dots could enhance the absorption of visible light by tuning the band gap of ZnO QDs, therefore increasing the photocurrent under visible irradiation.”

“This work indicates that the coupled use of Cu and Sm in ZnO nanorod array films have the potential to enhance the performance of dye-sensitized solar cells.”

“In addition, we visualize various metal-support interactions between Cu and ZnO under reaction conditions, e.g., ZnO clusters precipitating on Cu nanoparticles, which are critical to understand active sites of Cu/ZnO as catalysts for WGSR.”

“Our study shows that the photocatalytic activity of ZnO toward MB degradation under visible light can be effectively enhanced by doping it with Cu.”

“The addition of Cu to ZnO served to transform nanoclusters into nanorods as revealed during SEM analysis.”

“ Cu , Co and Ni species can slow the ZnO loss due to the priority for the reduction of these metal oxides and the formation of metal-Zn intermetallics.”

“The doping with Ni/Cu or Cu not only improves the crystalline quality but also significantly suppresses the density of deep-level emission defects in as-grown ZnO nanorods, as demonstrated by X-ray diffraction and photoluminescence.”
