Possible Interaction: Zinc Oxide and Iron, Dietary

“Here, ZnO NMs are doped with increasing levels of Fe , which allows to finely tune their dissolution rate resulting in significant differences in their biological behavior on cancer or normal cells.”

“Overall, results show that the modification of ZnO with iron or copper oxides enhances the hydrophobic behavior of the surface, increasing the contact angle of the water drops at the non-modified ZnO structures from 122° to 135° and 145° for Fe2O3@ZnO and CuO@ZnO, respectively.”

“ Fe based catalysts noticeably accelerated the loss of ZnO , which can be ascribed to the high oxophilicity of Fe and the strong interactions between the metal and support.”

“It can be concluded that the adsorption of iron will promote the separation of photoinduced carriers, thus improving the photocatalytic activity of ZnO (0001) surface.”

“The electrostatic potential computation reveals that the work function of the ZnO (0001) surface is significantly decreased from 2.340 to 1.768 eV when iron is adsorbed on the Top site.”

“The combination of scanning electron microscopy … in situ photoemission spectroscopy indicate that Fe enhances … ZnO etching, and that the CNT synthesis is favoured by the reduced Fe mobility due to the strong … between Fe and the NRs, and to the presence of many defects, formed during the CVD process.”

“The photo-activity of ZnO reduces Fe from 3+ to 2+ in the surface region of the nano-crystalline material due to the formation of oxygen vacancies.”

“ ZnO doped with a small amount of Fe or Cu decreased the size of the nanoparticles and the band gap and increased photocatalytic efficiency.”

“Doping with iron has red-shifted the absorption edges of ZnO towards the visible portion resulting in lower band gap energies with increasing dopant concentration.”
