Abstract In this work, the oxidation of sponge‐like nanostructured Zn films exploiting their interaction with water in liquid and vapor phases is investigated. By simply exposing sputtered porous metal layers to a atmosphere or incubating them at different temperatures, full conversion ZnO obtained. Depending on kind treatment, oxidized exhibit morphologies physico‐chemical properties. When com...

zno and tio2 nanoparticles wereimpregnated with merbromin dye and used as modified photocatalysts for degradation of phenol. dye-modified zno and tio2 showed significantly higher photocatalytic activity than neat zno and tio2 under visible light illumination. moreover, the prepared dye-modified zno showed superior photocatalytic efficiency in degradation of phenol compared to the dye-modified t...
