Abstract
A study is presented on the sensitivity of electrochemically deposited ZrO2 and ZnO on a quartz resonator. The nanostructured ZrO2 and ZnO layers are deposited by electrochemical method on the Au electrodes of the quartz resonators. The deposition of the electrochemical layers of ZrO2 and ZnO is carried out in aqueous solution of (ZrOCl2 (5. 10-3 M) and KCl (0.1 M) for ZrO2 and (ZnCl2 (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 ZrO2 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 ZrO2 and ZnO sorption properties is investigated. The sorption ability of the ZrO2 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).
