Abstract

Preparation of photocatalytically active ZnO layer by chemical bath deposition was investigated. Layers of layered basic zinc acetate (LBZA) were successfully deposited on substrates of varying morphologies, and the substrate hydrolysis led to formation of thicker and better adhering layers. However, the process was quite sensitive to variations in conditions, which makes coating of larger surfaces more challenging. Photocatalytic activity of ZnO layers obtained from LBZA by calcining had poor reproducibility, varying up to 50 % without obvious regularity.
