Effect of Ag content on the nanostructure and antimicrobial activity of CeO.

The morphological and antibacterial effects of CeO nanoparticles (NPs) with different amounts of Ag precursor were studied. The samples were synthesized with different percentages of silver nitrate content by co-precipitation method. The cerium nitrate hexahydrate was a precursor of Ce reagent, polyvinylpyrrolidone as dispersant agent, and ammonium hydroxide as a precipitating agent.

Influence of ruthenium doping on UV- and visible-light photoelectrocatalytic color removal from dye solutions using a TiO nanotube array photoanode.

The photocatalytic activity of TiO anodes was enhanced by synthesizing Ru-doped Ti|TiO nanotube arrays. Such photoanodes were fabricated via Ti anodization followed by Ru impregnation and annealing. The X-ray diffractograms revealed that anatase was the main TiO phase, while rutile was slightly present in all samples.
