Abstract
Thin films based on gallium oxide (β-Ga2O3) and mesoporous titanium oxide (TiO2 (MZ)) were successfully obtained by deposition on fluorine-doped tin oxide (FTO) conductive glass, using Doctor Blade method in two steps. Firstly, the β-Ga2O3 powders was synthesized by a simple and rapid microwave-assisted hydrothermal method followed by the calcination at 900° C for 3 hours. For the TiO2 (MZ) powders a sol-gel method was chosen to obtain the crystalline materials. Secondly, a stock pasta based on as-synthesized powders and a mixed solution of ethyl cellulose and α-terpineol was used for deposition of thin films by Doctor Blade method, obtaining the FTO/β-Ga2O3 and FTO/TiO2(MZ) thin films. The as-obtained structures were assessed for structural, optical, and morphological properties by X-ray diffraction, Ultraviolet-visible spectroscopy and SEM microscopy. The electrochemical properties were investigated by EIS and CV in 1M Na2SO4 supporting electrolyte at scan range -0.3 V/SCE and 0.5 V/SCE. These obtained results provide new insights into the development of highperformance and cost-effective FTO-based oxide thin films for electrochemical applications.
