Simple way for preparation of ZnO films by surfactant mediated spray pyrolysis

Nanocrystalline porous ZnO films are deposited onto alumina foil substrates by polyvinyl
alcohol (PVA) modified spray pyrolysis. Water and ethanol–water mixture were used for
preparation of the sols. The effect of polyvinyl alcohol on the morphological and
photocatalytical properties of ZnO films was studied. It was found that the polyvinyl alcohol
plays important role in formation of porous films structure with ganglia like morphology.
Relatively compact granular morphology was observed for the ZnO samples, grown without …
