Liquid Phase Deposition of TiO2 on a Multifunctional Template of Grafted Gallic Acid and Hexamethylenediamine (GAHD) with Enhanced Electrochemical Properties
Liquid phase deposition is a cost-effective and energy-efficient method for obtaining TiO2films at low temperatures. This work demonstrates the use of a multifunctional template consisting of grafted gallic acid (GA) and hexamethylenediamine (HD) on a Ti substrate to regulate the deposition of TiO2films. X-ray diffraction characterization shows that films deposited with the template have a more obvious anatase phase compared to direct deposition at 25 °C. The intensity of photoluminescence spectra also shows significant differences at 373.7 nm and 663.3 nm. Furthermore, electrochemical measurements indicate that TiO2films adjusted by the template have excellent electrochemical conversion properties. This proposed method provides a new simple route for fabricating TiO2films that are adjusted by GAHD templates, which may have good applications in the fields of semiconductor materials and biological materials.Keywords:titanium dioxide;GAHD;template adjusted deposition;liquid phase deposition
