Název v původním jazyce

Growth mechanism and photocatalytic properties for dye degradation of hydrophobic mesoporous ZnO/SDS films prepared by electrodeposition

Popis výsledku v původním jazyce

The growth by electrodeposition of ZnO/SDS hybrid thin films from aqueous mixed solution of zinc chloride and sodium dodecylsulfate (SDS), an anionic surfactant, using molecular oxygen as a precursor, has been studied. Significant morphological changes have been observed with the deposition time. At low electrodeposition time the layer is composed of flake-shaped aggregated grains whereas for a time longer than 10-15 min an inner layer composed of aggregated particles appears below the flake-type one. The flakes have a lamellar structure oriented parallel to the substrate. Krypton adsorption experiments show that the mesoporosity of the films is due to pores larger than 8 nm and probably arises from the nanoparticulate phase. The as-deposited films arehydrophobic with contact angles ranging between 110 degrees and 130 degrees. The hydrophobic character of these mesoporous ZnO films is found to substantially improve the efficiency of ZnO films for methylene blue photodegradation,...
