A study is presented on the sensitivity of electrochemically deposited ZrO 2 and ZnO on a quartz resonator. The nanostructured ZrO 2 and ZnO layers are deposited by electrochemical method on the Au electrodes of the quartz resonators. The deposition of the electrochemical layers of ZrO 2 and ZnO is carried out in aqueous solution of (ZrOCl 2 (5. 10 -3 M) and KCl (0.1 M) for ZrO 2 and (ZnCl 2 (5. 10 -3 M) and KCl (0.1 M) for ZnO) at 70°C and (vs SCE) using a three-electrode electrochemical cell. The structure of the ZrO 2 and ZnO layers deposited on the polished surface of quartz resonator is studied by Scanning Electron Microscopy (SEM) and optical profilometry. The influence of the roughness on the ZrO 2 and ZnO sorption properties is investigated. The sorption ability of the ZrO 2 and ZnO layers is defined by measuring the resonant frequency shift (ΔF) of the quartz structure in the presence of different concentration of methanol, ethanol and ammonia (0 - 25000 ppm).
