In this study, we use the chemical oxidation method to prepare the titania layer on titanium bulks. The oxidation time and temperature will be changed in the H2O2 solution to prepare porous network structure titania layer of different thickness and surface properties. An investigation of the formation mechanism of the network structure was also discussed. After oxidation, the SEM showed the maximum thickness of titania layer was about 3 μm. Porosity of titania layer was 50%; the XRD measurement showed that crystallographic structure of the titania layers were amorphous; and the XPS result showed that O/Ti ratio is increasing with oxidation time. After oxidation for 30, 60 and 90 min, the OS/OT ratio increase to 28%, 33% and 35% respectively. After modification with stearic acid, the contact angle of the titania layer was change from hydrophilic to hydrophobic, and XPS result showed the high reaction temperature enhanced reactivity of stearic acid to form the Ti-O-C ester-linkage. The ratios of OS/OL were decreasing with the amount of chemisorbed stearic acid due to the conversion of Ti-O-H to Ti-O-C.
The adsorption and photodegradation of methylene blue and cibacron blue onto amorphous titania network was studied. The Optimum pH value was observed above 6.5 for methylene blue and below 2.5 for cibacron blue. The titania layer exhibited excellent adsorption capability for methylene blue that is much superior to commercial TiO2 (Degussa P-25) with a broad pH range. And it was observed that the photodegradation efficiency of methylene blue on titania layer was less than P-25 powder due to the amorphous phase. Furthermore, a rough surface provides more adsorption sites in the adsorption and photodegradation processes, the cracks may allow dye to diffuse into the titania layer easily. So we consider that diversity in adsorption capability and photodegradation efficiency was not only cause by the crystal phase, but also the different in zero point of charge, quantity of hydroxyl groups and the surface morphology
